///
/// @RESTDESCRIPTION
///
/// The transaction description must be passed in the body of the POST request.
///
/// The following attributes must be specified inside the JSON object:
///
/// - *collections*: contains the list of collections to be used in the
/// transaction (mandatory). *collections* must be a JSON array that can
/// have the optional sub-attributes *read* and *write*. *read*
/// and *write* must each be either lists of collections names or strings
/// with a single collection name.
///
/// - *action*: the actual transaction operations to be executed, in the
/// form of stringified Javascript code. The code will be executed on server
/// side, with late binding. It is thus critical that the code specified in
/// *action* properly sets up all the variables it needs.
/// If the code specified in *action* ends with a return statement, the
/// value returned will also be returned by the REST API in the *result*
/// attribute if the transaction committed successfully.
///
/// The following optional attributes may also be specified in the request:
///
/// - *waitForSync*: an optional boolean flag that, if set, will force the
/// transaction to write all data to disk before returning.
///
/// - *lockTimeout*: an optional numeric value that can be used to set a
/// timeout for waiting on collection locks. If not specified, a default
/// value will be used. Setting *lockTimeout* to *0* will make ArangoDB
/// not time out waiting for a lock.
///
/// - *params*: optional arguments passed to *action*.
///
/// If the transaction is fully executed and committed on the server,
/// *HTTP 200* will be returned. Additionally, the return value of the
/// code defined in *action* will be returned in the *result* attribute.
///
/// For successfully committed transactions, the returned JSON object has the
/// following properties:
///
/// - *error*: boolean flag to indicate if an error occurred (*false*
/// in this case)
///
/// - *code*: the HTTP status code
///
/// - *result*: the return value of the transaction
///
/// If the transaction specification is either missing or malformed, the server
/// will respond with *HTTP 400*.
///
/// The body of the response will then contain a JSON object with additional error
/// details. The object has the following attributes:
///
/// - *error*: boolean flag to indicate that an error occurred (*true* in this case)
///
/// - *code*: the HTTP status code
///
/// - *errorNum*: the server error number
///
/// - *errorMessage*: a descriptive error message
///
/// If a transaction fails to commit, either by an exception thrown in the
/// *action* code, or by an internal error, the server will respond with
/// an error.
/// Any other errors will be returned with any of the return codes
/// *HTTP 400*, *HTTP 409*, or *HTTP 500*.
///
/// @RESTRETURNCODES
///
/// @RESTRETURNCODE{200}
/// If the transaction is fully executed and committed on the server,

//
// About: Support and Testing
//
// Information about what version or versions of jQuery this plugin has been
// tested with, what browsers it has been tested in, and where the unit tests
// reside (so you can test it yourself).
//
// jQuery Versions - 1.2.6, 1.3.2, 1.4.1, 1.4.2
// Browsers Tested - Internet Explorer 6-8, Firefox 2-4, Chrome 5-6, Safari 3.2-5,
// Opera 9.6-10.60, iPhone 3.1, Android 1.6-2.2, BlackBerry 4.6-5.
// Unit Tests - http://benalman.com/code/projects/jquery-hashchange/unit/
//
// About: Known issues
//
// While this jQuery hashchange event implementation is quite stable and
// robust, there are a few unfortunate browser bugs surrounding expected
// hashchange event-based behaviors, independent of any JavaScript
// window.onhashchange abstraction. See the following examples for more
// information:
//
// Chrome: Back Button - http://benalman.com/code/projects/jquery-hashchange/examples/bug-chrome-back-button/
// Firefox: Remote XMLHttpRequest - http://benalman.com/code/projects/jquery-hashchange/examples/bug-firefox-remote-xhr/
// WebKit: Back Button in an Iframe - http://benalman.com/code/projects/jquery-hashchange/examples/bug-webkit-hash-iframe/
// Safari: Back Button from a different domain - http://benalman.com/code/projects/jquery-hashchange/examples/bug-safari-back-from-diff-domain/
//
// Also note that should a browser natively support the window.onhashchange
// event, but not report that it does, the fallback polling loop will be used.
//
// About: Release History
//
// 1.3 - (7/21/2010) Reorganized IE6/7 Iframe code to make it more
// "removable" for mobile-only development. Added IE6/7 document.title
// support. Attempted to make Iframe as hidden as possible by using
// techniques from http://www.paciellogroup.com/blog/?p=604. Added
// support for the "shortcut" format $(window).hashchange( fn ) and
// $(window).hashchange() like jQuery provides for built-in events.
// Renamed jQuery.hashchangeDelay to <jQuery.fn.hashchange.delay> and
// lowered its default value to 50. Added <jQuery.fn.hashchange.domain>
// and <jQuery.fn.hashchange.src> properties plus document-domain.html
// file to address access denied issues when setting document.domain in
// IE6/7.
// 1.2 - (2/11/2010) Fixed a bug where coming back to a page using this plugin
// from a page on another domain would cause an error in Safari 4. Also,
// IE6/7 Iframe is now inserted after the body (this actually works),
// which prevents the page from scrolling when the event is first bound.
// Event can also now be bound before DOM ready, but it won't be usable
// before then in IE6/7.
// 1.1 - (1/21/2010) Incorporated document.documentMode test to fix IE8 bug
// where browser version is incorrectly reported as 8.0, despite
// inclusion of the X-UA-Compatible IE=EmulateIE7 meta tag.
// 1.0 - (1/9/2010) Initial Release. Broke out the jQuery BBQ event.special
// window.onhashchange functionality into a separate plugin for users
// who want just the basic event & back button support, without all the
// extra awesomeness that BBQ provides. This plugin will be included as
// part of jQuery BBQ, but also be available separately.
(function ($, window, undefined) {
// Reused string.
var str_hashchange = 'hashchange',
// Method / object references.
doc = document,
fake_onhashchange,
special = $.event.special,
// Does the browser support window.onhashchange? Note that IE8 running in
// IE7 compatibility mode reports true for 'onhashchange' in window, even
// though the event isn't supported, so also test document.documentMode.

// Method: jQuery.fn.hashchange
//
// Bind a handler to the window.onhashchange event or trigger all bound
// window.onhashchange event handlers. This behavior is consistent with
// jQuery's built-in event handlers.
//
// Usage:
//
// > jQuery(window).hashchange( [ handler ] );
//
// Arguments:
//
// handler - (Function) Optional handler to be bound to the hashchange
// event. This is a "shortcut" for the more verbose form:
// jQuery(window).bind( 'hashchange', handler ). If handler is omitted,
// all bound window.onhashchange event handlers will be triggered. This
// is a shortcut for the more verbose
// jQuery(window).trigger( 'hashchange' ). These forms are described in
// the <hashchange event> section.
//
// Returns:
//
// (jQuery) The initial jQuery collection of elements.
// Allow the "shortcut" format $(elem).hashchange( fn ) for binding and
// $(elem).hashchange() for triggering, like jQuery does for built-in events.
$.fn[ str_hashchange ] = function (fn) {
return fn ? this.bind(str_hashchange, fn) : this.trigger(str_hashchange);
};
// Property: jQuery.fn.hashchange.delay
//
// The numeric interval (in milliseconds) at which the <hashchange event>
// polling loop executes. Defaults to 50.
// Property: jQuery.fn.hashchange.domain
//
// If you're setting document.domain in your JavaScript, and you want hash
// history to work in IE6/7, not only must this property be set, but you must
// also set document.domain BEFORE jQuery is loaded into the page. This
// property is only applicable if you are supporting IE6/7 (or IE8 operating
// in "IE7 compatibility" mode).
//
// In addition, the <jQuery.fn.hashchange.src> property must be set to the
// path of the included "document-domain.html" file, which can be renamed or
// modified if necessary (note that the document.domain specified must be the
// same in both your main JavaScript as well as in this file).
//
// Usage:
//
// jQuery.fn.hashchange.domain = document.domain;
// Property: jQuery.fn.hashchange.src
//
// If, for some reason, you need to specify an Iframe src file (for example,
// when setting document.domain as in <jQuery.fn.hashchange.domain>), you can
// do so using this property. Note that when using this property, history
// won't be recorded in IE6/7 until the Iframe src file loads. This property
// is only applicable if you are supporting IE6/7 (or IE8 operating in "IE7
// compatibility" mode).
//
// Usage:
//
// jQuery.fn.hashchange.src = 'path/to/file.html';
$.fn[ str_hashchange ].delay = 50;
/*
$.fn[ str_hashchange ].domain = null;
$.fn[ str_hashchange ].src = null;
*/
// Event: hashchange event
//
// Fired when location.hash changes. In browsers that support it, the native
// HTML5 window.onhashchange event is used, otherwise a polling loop is
// initialized, running every <jQuery.fn.hashchange.delay> milliseconds to
// see if the hash has changed. In IE6/7 (and IE8 operating in "IE7
// compatibility" mode), a hidden Iframe is created to allow the back button
// and hash-based history to work.
//
// Usage as described in <jQuery.fn.hashchange>:
//
// > // Bind an event handler.
// > jQuery(window).hashchange( function(e) {
// > var hash = location.hash;
// > ...
// > });
// >
// > // Manually trigger the event handler.
// > jQuery(window).hashchange();
//
// A more verbose usage that allows for event namespacing:
//
// > // Bind an event handler.
// > jQuery(window).bind( 'hashchange', function(e) {
// > var hash = location.hash;
// > ...
// > });
// >
// > // Manually trigger the event handler.
// > jQuery(window).trigger( 'hashchange' );
//
// Additional Notes:
//
// * The polling loop and Iframe are not created until at least one handler
// is actually bound to the 'hashchange' event.
// * If you need the bound handler(s) to execute immediately, in cases where
// a location.hash exists on page load, via bookmark or page refresh for
// example, use jQuery(window).hashchange() or the more verbose
// jQuery(window).trigger( 'hashchange' ).
// * The event can be bound before DOM ready, but since it won't be usable

//
// Why do we have to rely on proximity?
//
// Because the target of the touch event that triggered the vclick
// can be different from the target of the click event synthesized
// by the browser. The target of a mouse/click event that is syntehsized
// from a touch event seems to be implementation specific. For example,
// some browsers will fire mouse/click events for a link that is near
// a touch event, even though the target of the touchstart/touchend event
// says the user touched outside the link. Also, it seems that with most
// browsers, the target of the mouse/click event is not calculated until the
// time it is dispatched, so if you replace an element that you touched
// with another element, the target of the mouse/click will be the new
// element underneath that point.
//
// Aside from proximity, we also check to see if the target and any
// of its ancestors were the ones that blocked a click. This is necessary
// because of the strange mouse/click target calculation done in the
// Android 2.1 browser, where if you click on an element, and there is a
// mouse/click handler on one of its ancestors, the target will be the
// innermost child of the touched element, even if that child is no where
// near the point of touch.

Implementation Summary
1. Enforce API surface and semantic compatibility with 1.9.x branch
2. Improve the module's maintainability by reducing the storage
paths to a single mechanism.
3. Use the same single mechanism to support "private" and "user" data.
4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
5. Avoid exposing implementation details on user objects (eg. expando properties)
6. Provide a clear path for implementation upgrade to WeakMap in 2014

* - `process.nextTick` is only Node.js.

* - Everything else is browser based (e.g., mutation observer, requestAnimationFrame, etc).
* - Only API which is universal is `setTimeout`.
* - Note that `0` is not actually `0ms`. Browser environments commonly have a minimum delay of `4ms`. This is acceptable. Here, the main intent of this function is to give the runtime a chance to run garbage collection, clear state, and tend to any other pending tasks before returning control to benchmark tasks. The larger aim (attainable or not) is to provide each benchmark run with as much of a fresh state as possible.

/**
* Evaluates the exponential function.
*
* ## Method
*
* 1. Let \\(x = 2^n (1+f)\\).
*
* 2. Compute \\(\operatorname{log2}(x)\\) as
*
* ```tex
* \operatorname{log2}(x) = w_1 + w_2
* ```
*
* where \\(w_1\\) has \\(53 - 24 = 29\\) bit trailing zeros.
*
* 3. Compute
*
* ```tex
* y \cdot \operatorname{log2}(x) = n + y^\prime
* ```
*
* by simulating multi-precision arithmetic, where \\(|y^\prime| \leq 0.5\\).
*
* 4. Return
*
* ```tex
* x^y = 2^n e^{y^\prime \cdot \mathrm{log2}}
* ```
*
* ## Special Cases
*
* ```tex
* \begin{align*}
* x^{\mathrm{NaN}} &= \mathrm{NaN} & \\
* (\mathrm{NaN})^y &= \mathrm{NaN} & \\
* 1^y &= 1 & \\
* x^0 &= 1 & \\
* x^1 &= x & \\
* (\pm 0)^\infty &= +0 & \\
* (\pm 0)^{-\infty} &= +\infty & \\
* (+0)^y &= +0 & \mathrm{if}\ y > 0 \\
* (+0)^y &= +\infty & \mathrm{if}\ y < 0 \\
* (-0)^y &= -\infty & \mathrm{if}\ y\ \mathrm{is\ an\ odd\ integer\ and}\ y < 0 \\
* (-0)^y &= +\infty & \mathrm{if}\ y\ \mathrm{is\ not\ an\ odd\ integer\ and}\ y < 0 \\
* (-0)^y &= -0 & \mathrm{if}\ y\ \mathrm{is\ an\ odd\ integer\ and}\ y > 0 \\
* (-0)^y &= +0 & \mathrm{if}\ y\ \mathrm{is\ not\ an\ odd\ integer\ and}\ y > 0 \\
* (-1)^{\pm\infty} &= \mathrm{NaN} & \\
* x^{\infty} &= +\infty & |x| > 1 \\
* x^{\infty} &= +0 & |x| < 1 \\
* x^{-\infty} &= +0 & |x| > 1 \\
* x^{-\infty} &= +\infty & |x| < 1 \\
* (-\infty)^y &= (-0)^y & \\
* \infty^y &= +0 & y < 0 \\
* \infty^y &= +\infty & y > 0 \\
* x^y &= \mathrm{NaN} & \mathrm{if}\ y\ \mathrm{is\ not\ a\ finite\ integer\ and}\ x < 0
* \end{align*}
* ```
*
* ## Notes
*
* - \\(\operatorname{pow}(x,y)\\) returns \\(x^y\\) nearly rounded. In particular, \\(\operatorname{pow}(<\mathrm{integer}>,<\mathrm{integer}>)\\) **always** returns the correct integer, provided the value is representable.
* - The hexadecimal values shown in the source code are the intended values for used constants. Decimal values may be used, provided the compiler will accurately convert decimal to binary in order to produce the hexadecimal values.

*
* ```tex
* a = w_h*2^{16} + w_l

*
* ```binarystring
* 11111111111111111111111111111111
* ```

* ```binarystring
* 1111111111111111

* If we cast the high word to 32-bit precision and multiply by \\( 2^{16} \\) (equivalent to a 16-bit left shift), then the bit sequence is
*
* ```binarystring
* 11111111111111110000000000000000
* ```
*
* Similarly, upon casting the low word to 32-bit precision, the bit sequence is
*
* ```binarystring
* 00000000000000001111111111111111
* ```
*
* From the rules of binary addition, we recognize that adding the two 32-bit values for the high and low words will return our original value \\( 2^{32}-1 \\).
*
* - Accordingly, the multiplication of two 32-bit integers can be expressed
*
* ```tex
* \begin{align*}
* a \cdot b &= ( a_h \cdot 2^{16} + a_l) \cdot ( b_h \cdot 2^{16} + b_l) \\
* &= a_l \cdot b_l + a_h \cdot b_l \cdot 2^{16} + a_l \cdot b_h \cdot 2^{16} + (a_h \cdot b_h) \cdot 2^{32} \\
* &= a_l \cdot b_l + (a_h \cdot b_l + a_l \cdot b_h) \cdot 2^{16} + (a_h \cdot b_h) \cdot 2^{32}
* \end{align*}
* ```
*
* - We note that multiplying (dividing) an integer by \\( 2^n \\) is equivalent to performing a left (right) shift of \\( n \\) bits.
*
* - Further, as we want to return an integer of the same precision, for a 32-bit integer, the return value will be modulo \\( 2^{32} \\). Stated another way, we only care about the low word of a 64-bit result.
*
* - Accordingly, the last term, being evenly divisible by \\( 2^{32} \\), drops from the equation leaving the remaining two terms as the remainder.
*
* ```tex
* a \cdot b = a_l \cdot b_l + (a_h \cdot b_l + a_l \cdot b_h) << 16
* ```
*
* - Lastly, the second term in the above equation contributes to the middle bits and may cause the product to "overflow". However, we can disregard (`>>>0`) overflow bits due modulo arithmetic, as discussed earlier with regard to the term involving the partial product of high words.
*
*
* @param {uinteger32} a - integer
* @param {uinteger32} b - integer

* var v = uimul( 10>>>0, 4>>>0 );

/**
* Generates a pseudorandom integer on the interval \\( [1,2^{31}-1) \\).
*
* ## Method
*
* Linear congruential generators (LCGs) use the recurrence relation
*
* ```tex
* X_{n+1} = ( a \cdot X_n + c ) \operatorname{mod}(m)
* ```
*
* where the modulus \\( m \\) is a prime number or power of a prime number and \\( a \\) is a primitive root modulo \\( m \\).
*
* <!-- <note> -->
*
* For an LCG to be a Lehmer RNG, the seed \\( X_0 \\) must be coprime to \\( m \\).
*
* <!-- </note> -->
*
* In this implementation, the constants \\( a \\), \\( c \\), and \\( m \\) have the values
*
* ```tex
* \begin{align*}
* a &= 7^5 = 16807 \\
* c &= 0 \\
* m &= 2^{31} - 1 = 2147483647
* \end{align*}
* ```
*
* <!-- <note> -->
*
* The constant \\( m \\) is a Mersenne prime (modulo \\(31\\)).
*
* <!-- </note> -->
*
* <!-- <note> -->
*
* The constant \\( a \\) is a primitive root (modulo \\(31\\)).
*
* <!-- </note> -->
*
* Accordingly, the maximum possible product is
*
* ```tex
* 16807 \cdot (m - 1) \approx 2^{46}
* ```
*
* The values for \\( a \\), \\( c \\), and \\( m \\) are taken from Park and Miller, "Random Number Generators: Good Ones Are Hard To Find". Park's and Miller's article is also the basis for a recipe in the second edition of _Numerical Recipes in C_.
*
* This implementation subsequently shuffles the output of a linear congruential pseudorandom number generator (LCG) using a shuffle table in accordance with the Bays-Durham algorithm.
*
*
* ## Notes
*
* - The generator has a period of approximately \\(2.1\mbox{e}9\\) (see [Numerical Recipes in C, 2nd Edition](#references), p. 279).

/**
* Generates a pseudorandom integer on the interval \\( [1,2^{31}-1) \\).
*
* ## Method
*
* Linear congruential generators (LCGs) use the recurrence relation
*
* ```tex
* X_{n+1} = ( a \cdot X_n + c ) \operatorname{mod}(m)
* ```
*
* where the modulus \\( m \\) is a prime number or power of a prime number and \\( a \\) is a primitive root modulo \\( m \\).
*
* <!-- <note> -->
*
* For an LCG to be a Lehmer RNG, the seed \\( X_0 \\) must be coprime to \\( m \\).
*
* <!-- </note> -->
*
* In this implementation, the constants \\( a \\), \\( c \\), and \\( m \\) have the values
*
* ```tex
* \begin{align*}
* a &= 7^5 = 16807 \\
* c &= 0 \\
* m &= 2^{31} - 1 = 2147483647
* \end{align*}
* ```
*
* <!-- <note> -->
*
* The constant \\( m \\) is a Mersenne prime (modulo \\(31\\)).
*
* <!-- </note> -->
*
* <!-- <note> -->
*
* The constant \\( a \\) is a primitive root (modulo \\(31\\)).
*
* <!-- </note> -->
*
* Accordingly, the maximum possible product is
*
* ```tex
* 16807 \cdot (m - 1) \approx 2^{46}
* ```
*
* The values for \\( a \\), \\( c \\), and \\( m \\) are taken from Park and Miller, "Random Number Generators: Good Ones Are Hard To Find". Park's and Miller's article is also the basis for a recipe in the second edition of _Numerical Recipes in C_.
*
*
* ## Notes
*
* - The generator has a period of approximately \\(2.1\mbox{e}9\\) (see [Numerical Recipes in C, 2nd Edition](#references), p. 279).

/**
* Generates a pseudorandom integer on the interval \\( [1,2^{32}-1) \\).
*
* ## Method
*
* - When generating normalized double-precision floating-point numbers, we first generate two pseudorandom integers \\( x \\) and \\( y \\) on the interval \\( [1,2^{32}-1) \\) for a combined \\( 64 \\) random bits.
*
* - We would like \\( 53 \\) random bits to generate a 53-bit precision integer and, thus, want to discard \\( 11 \\) of the generated bits.
*
* - We do so by discarding \\( 5 \\) bits from \\( x \\) and \\( 6 \\) bits from \\( y \\).
*
* - Accordingly, \\( x \\) contains \\( 27 \\) random bits, which are subsequently shifted left \\( 26 \\) bits (multiplied by \\( 2^{26} \\), and \\( y \\) contains \\( 26 \\) random bits to fill in the lower \\( 26 \\) bits. When summed, they combine to comprise \\( 53 \\) random bits of a double-precision floating-point integer.
*
* - As an example, suppose, for the sake of argument, the 32-bit PRNG generates the maximum unsigned 32-bit integer \\( 2^{32}-1 \\) twice in a row. Then,
*
* ```javascript
* x = 4294967295 >>> 5; // 00000111111111111111111111111111
* y = 4294967295 >>> 6; // 00000011111111111111111111111111
* ```
*
* Multiplying \\( x \\) by \\( 2^{26} \\) returns \\( 9007199187632128 \\), which, in binary, is
*
* ```binarystring
* 0 10000110011 11111111111111111111 11111100000000000000000000000000
* ```
*
* Adding \\( y \\) yields \\( 9007199254740991 \\) (the maximum "safe" double-precision floating-point integer value), which, in binary, is
*
* ```binarystring
* 0 10000110011 11111111111111111111 11111111111111111111111111111111
* ```
*
* - Similarly, suppose the 32-bit PRNG generates the following values
*
* ```javascript
* x = 1 >>> 5; // 0 => 00000000000000000000000000000000
* y = 64 >>> 6; // 1 => 00000000000000000000000000000001
* ```
*
* Multiplying \\( x \\) by \\( 2^{26} \\) returns \\( 0 \\), which, in binary, is
*
* ```binarystring
* 0 00000000000 00000000000000000000 00000000000000000000000000000000
* ```
*
* Adding \\( y \\) yields \\( 1 \\), which, in binary, is
*
* ```binarystring
* 0 01111111111 00000000000000000000 00000000000000000000000000000000
* ```
*
* - As different combinations of \\( x \\) and \\( y \\) are generated, different combinations of double-precision floating-point exponent and significand bits will be toggled, thus generating pseudorandom double-precision floating-point numbers.

*
* - In contrast to the built-in `Object.getOwnPropertyNames()`, this function returns an empty array if provided `undefined` or `null`, rather than throwing an error.
* - In environments lacking support for `Object.getOwnPropertyNames()`, property descriptors are unavailable, and thus all properties can be safely assumed to be enumerable. Hence, we can defer to calling `Object.keys`, which retrieves all own enumerable property names.

// a transform stream is a readable/writable stream where you do
// something with the data. Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored. (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation. For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes. When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up. When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer. When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks. If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk. However,
// a pathological inflate type of transform can cause excessive buffering
// here. For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output. In this case, you could write a very small
// amount of input, and end up with a very large amount of output. In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform. A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.

* - Everything else is browser based (e.g., mutation observer, requestAnimationFrame, etc).
* - Only API which is universal is `setTimeout`.
* - Note that `0` is not actually `0ms`. Browser environments commonly have a minimum delay of `4ms`. This is acceptable. Here, the main intent of this function is to give the runtime a chance to run garbage collection, clear state, and tend to any other pending tasks before returning control to benchmark tasks. The larger aim (attainable or not) is to provide each benchmark run with as much of a fresh state as possible.

* Performs C-like multiplication of two unsigned 32-bit integers.

* ## Method
*
* - To emulate C-like multiplication without the aid of 64-bit integers, we recognize that a 32-bit integer can be split into two 16-bit words
*
* ```tex
* a = w_h*2^{16} + w_l
* ```
*
* where \\( w_h \\) is the most significant 16 bits and \\( w_l \\) is the least significant 16 bits. For example, consider the maximum unsigned 32-bit integer \\( 2^{32}-1 \\)
*
* ```binarystring
* 11111111111111111111111111111111
* ```
*
* The 16-bit high word is then
*
* ```binarystring
* 1111111111111111
* ```
*
* and the 16-bit low word
*
* ```binarystring
* 1111111111111111
* ```
*
* If we cast the high word to 32-bit precision and multiply by \\( 2^{16} \\) (equivalent to a 16-bit left shift), then the bit sequence is
*
* ```binarystring
* 11111111111111110000000000000000
* ```
*
* Similarly, upon casting the low word to 32-bit precision, the bit sequence is
*
* ```binarystring
* 00000000000000001111111111111111
* ```
*
* From the rules of binary addition, we recognize that adding the two 32-bit values for the high and low words will return our original value \\( 2^{32}-1 \\).
*
* - Accordingly, the multiplication of two 32-bit integers can be expressed
*
* ```tex
* \begin{align*}
* a \cdot b &= ( a_h \cdot 2^{16} + a_l) \cdot ( b_h \cdot 2^{16} + b_l) \\
* &= a_l \cdot b_l + a_h \cdot b_l \cdot 2^{16} + a_l \cdot b_h \cdot 2^{16} + (a_h \cdot b_h) \cdot 2^{32} \\
* &= a_l \cdot b_l + (a_h \cdot b_l + a_l \cdot b_h) \cdot 2^{16} + (a_h \cdot b_h) \cdot 2^{32}
* \end{align*}
* ```
*
* - We note that multiplying (dividing) an integer by \\( 2^n \\) is equivalent to performing a left (right) shift of \\( n \\) bits.
*
* - Further, as we want to return an integer of the same precision, for a 32-bit integer, the return value will be modulo \\( 2^{32} \\). Stated another way, we only care about the low word of a 64-bit result.
*
* - Accordingly, the last term, being evenly divisible by \\( 2^{32} \\), drops from the equation leaving the remaining two terms as the remainder.
*
* ```tex
* a \cdot b = a_l \cdot b_l + (a_h \cdot b_l + a_l \cdot b_h) << 16
* ```
*
* - Lastly, the second term in the above equation contributes to the middle bits and may cause the product to "overflow". However, we can disregard (`>>>0`) overflow bits due modulo arithmetic, as discussed earlier with regard to the term involving the partial product of high words.
*
*
* @param {uinteger32} a - integer
* @param {uinteger32} b - integer
* @returns {uinteger32} product
*
* @example
* var v = uimul( 10>>>0, 4>>>0 );
* // returns 40

/**
* Generates a pseudorandom integer on the interval \\( [1,2^{31}-1) \\).
*
* ## Method
*
* Linear congruential generators (LCGs) use the recurrence relation
*
* ```tex
* X_{n+1} = ( a \cdot X_n + c ) \operatorname{mod}(m)
* ```
*
* where the modulus \\( m \\) is a prime number or power of a prime number and \\( a \\) is a primitive root modulo \\( m \\).
*
* <!-- <note> -->
*
* For an LCG to be a Lehmer RNG, the seed \\( X_0 \\) must be coprime to \\( m \\).
*
* <!-- </note> -->
*
* In this implementation, the constants \\( a \\), \\( c \\), and \\( m \\) have the values
*
* ```tex
* \begin{align*}
* a &= 7^5 = 16807 \\
* c &= 0 \\
* m &= 2^{31} - 1 = 2147483647
* \end{align*}
* ```
*
* <!-- <note> -->
*
* The constant \\( m \\) is a Mersenne prime (modulo \\(31\\)).
*
* <!-- </note> -->
*
* <!-- <note> -->
*
* The constant \\( a \\) is a primitive root (modulo \\(31\\)).
*
* <!-- </note> -->
*
* Accordingly, the maximum possible product is
*
* ```tex
* 16807 \cdot (m - 1) \approx 2^{46}
* ```
*
* The values for \\( a \\), \\( c \\), and \\( m \\) are taken from Park and Miller, "Random Number Generators: Good Ones Are Hard To Find". Park's and Miller's article is also the basis for a recipe in the second edition of _Numerical Recipes in C_.
*
* This implementation subsequently shuffles the output of a linear congruential pseudorandom number generator (LCG) using a shuffle table in accordance with the Bays-Durham algorithm.
*
*
* ## Notes
*
* - The generator has a period of approximately \\(2.1\mbox{e}9\\) (see [Numerical Recipes in C, 2nd Edition](#references), p. 279).

/**
* Generates a pseudorandom integer on the interval \\( [1,2^{31}-1) \\).
*
* ## Method
*
* Linear congruential generators (LCGs) use the recurrence relation
*
* ```tex
* X_{n+1} = ( a \cdot X_n + c ) \operatorname{mod}(m)
* ```
*
* where the modulus \\( m \\) is a prime number or power of a prime number and \\( a \\) is a primitive root modulo \\( m \\).
*
* <!-- <note> -->
*
* For an LCG to be a Lehmer RNG, the seed \\( X_0 \\) must be coprime to \\( m \\).
*
* <!-- </note> -->
*
* In this implementation, the constants \\( a \\), \\( c \\), and \\( m \\) have the values
*
* ```tex
* \begin{align*}
* a &= 7^5 = 16807 \\
* c &= 0 \\
* m &= 2^{31} - 1 = 2147483647
* \end{align*}
* ```
*
* <!-- <note> -->
*
* The constant \\( m \\) is a Mersenne prime (modulo \\(31\\)).
*
* <!-- </note> -->
*
* <!-- <note> -->
*
* The constant \\( a \\) is a primitive root (modulo \\(31\\)).
*
* <!-- </note> -->
*
* Accordingly, the maximum possible product is
*
* ```tex
* 16807 \cdot (m - 1) \approx 2^{46}
* ```
*
* The values for \\( a \\), \\( c \\), and \\( m \\) are taken from Park and Miller, "Random Number Generators: Good Ones Are Hard To Find". Park's and Miller's article is also the basis for a recipe in the second edition of _Numerical Recipes in C_.
*
*
* ## Notes
*
* - The generator has a period of approximately \\(2.1\mbox{e}9\\) (see [Numerical Recipes in C, 2nd Edition](#references), p. 279).

/**
* Generates a pseudorandom integer on the interval \\( [1,2^{32}-1) \\).
*
* ## Method
*
* - When generating normalized double-precision floating-point numbers, we first generate two pseudorandom integers \\( x \\) and \\( y \\) on the interval \\( [1,2^{32}-1) \\) for a combined \\( 64 \\) random bits.
*
* - We would like \\( 53 \\) random bits to generate a 53-bit precision integer and, thus, want to discard \\( 11 \\) of the generated bits.
*
* - We do so by discarding \\( 5 \\) bits from \\( x \\) and \\( 6 \\) bits from \\( y \\).
*
* - Accordingly, \\( x \\) contains \\( 27 \\) random bits, which are subsequently shifted left \\( 26 \\) bits (multiplied by \\( 2^{26} \\), and \\( y \\) contains \\( 26 \\) random bits to fill in the lower \\( 26 \\) bits. When summed, they combine to comprise \\( 53 \\) random bits of a double-precision floating-point integer.
*
* - As an example, suppose, for the sake of argument, the 32-bit PRNG generates the maximum unsigned 32-bit integer \\( 2^{32}-1 \\) twice in a row. Then,
*
* ```javascript
* x = 4294967295 >>> 5; // 00000111111111111111111111111111
* y = 4294967295 >>> 6; // 00000011111111111111111111111111
* ```
*
* Multiplying \\( x \\) by \\( 2^{26} \\) returns \\( 9007199187632128 \\), which, in binary, is
*
* ```binarystring
* 0 10000110011 11111111111111111111 11111100000000000000000000000000
* ```
*
* Adding \\( y \\) yields \\( 9007199254740991 \\) (the maximum "safe" double-precision floating-point integer value), which, in binary, is
*
* ```binarystring
* 0 10000110011 11111111111111111111 11111111111111111111111111111111
* ```
*
* - Similarly, suppose the 32-bit PRNG generates the following values
*
* ```javascript
* x = 1 >>> 5; // 0 => 00000000000000000000000000000000
* y = 64 >>> 6; // 1 => 00000000000000000000000000000001
* ```
*
* Multiplying \\( x \\) by \\( 2^{26} \\) returns \\( 0 \\), which, in binary, is
*
* ```binarystring
* 0 00000000000 00000000000000000000 00000000000000000000000000000000
* ```
*
* Adding \\( y \\) yields \\( 1 \\), which, in binary, is
*
* ```binarystring
* 0 01111111111 00000000000000000000 00000000000000000000000000000000
* ```
*
* - As different combinations of \\( x \\) and \\( y \\) are generated, different combinations of double-precision floating-point exponent and significand bits will be toggled, thus generating pseudorandom double-precision floating-point numbers.

* ## Notes
*
* - In contrast to the built-in `Object.getOwnPropertyNames()`, this function returns an empty array if provided `undefined` or `null`, rather than throwing an error.
* - In environments lacking support for `Object.getOwnPropertyNames()`, property descriptors are unavailable, and thus all properties can be safely assumed to be enumerable. Hence, we can defer to calling `Object.keys`, which retrieves all own enumerable property names.

// a transform stream is a readable/writable stream where you do
// something with the data. Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored. (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation. For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes. When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up. When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer. When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks. If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk. However,
// a pathological inflate type of transform can cause excessive buffering
// here. For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output. In this case, you could write a very small
// amount of input, and end up with a very large amount of output. In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform. A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.

* - Everything else is browser based (e.g., mutation observer, requestAnimationFrame, etc).
* - Only API which is universal is `setTimeout`.
* - Note that `0` is not actually `0ms`. Browser environments commonly have a minimum delay of `4ms`. This is acceptable. Here, the main intent of this function is to give the runtime a chance to run garbage collection, clear state, and tend to any other pending tasks before returning control to benchmark tasks. The larger aim (attainable or not) is to provide each benchmark run with as much of a fresh state as possible.

/**
* Evaluates the natural exponential function.
*
* ## Method
*
* 1. We reduce \\( x \\) to an \\( r \\) so that \\( |r| \leq 0.5 \cdot \ln(2) \approx 0.34658 \\). Given \\( x \\), we find an \\( r \\) and integer \\( k \\) such that
*
* ```tex
* \begin{align*}
* x &= k \cdot \ln(2) + r \\
* |r| &\leq 0.5 \cdot \ln(2)
* \end{align*}
* ```
*
* <!-- <note> -->
*
* \\( r \\) can be represented as \\( r = \mathrm{hi} - \mathrm{lo} \\) for better accuracy.
*
* <!-- </note> -->
*
* 2. We approximate of \\( e^{r} \\) by a special rational function on the interval \\(\[0,0.34658]\\):
*
* ```tex
* \begin{align*}
* R\left(r^2\right) &= r \cdot \frac{ e^{r}+1 }{ e^{r}-1 } \\
* &= 2 + \frac{r^2}{6} - \frac{r^4}{360} + \ldots
* \end{align*}
* ```
*
* We use a special Remes algorithm on \\(\[0,0.34658]\\) to generate a polynomial of degree \\(5\\) to approximate \\(R\\). The maximum error of this polynomial approximation is bounded by \\(2^{-59}\\). In other words,
*
* ```tex
* R(z) \sim 2 + P_1 z + P_2 z^2 + P_3 z^3 + P_4 z^4 + P_5 z^5
* ```
*
* where \\( z = r^2 \\) and
*
* ```tex
* \left| 2 + P_1 z + \ldots + P_5 z^5 - R(z) \right| \leq 2^{-59}
* ```
*
* <!-- <note> -->
*
* The values of \\( P_1 \\) to \\( P_5 \\) are listed in the source code.
*
* <!-- </note> -->
*
* The computation of \\( e^{r} \\) thus becomes
*
* ```tex
* \begin{align*}
* e^{r} &= 1 + \frac{2r}{R-r} \\
* &= 1 + r + \frac{r \cdot R_1(r)}{2 - R_1(r)}\ \text{for better accuracy}
* \end{align*}
* ```
*
* where
*
* ```tex
* R_1(r) = r - P_1\ r^2 + P_2\ r^4 + \ldots + P_5\ r^{10}
* ```
*
* 3. We scale back to obtain \\( e^{x} \\). From step 1, we have
*
* ```tex
* e^{x} = 2^k e^{r}
* ```
*
*
* ## Special Cases
*
* ```tex
* \begin{align*}
* e^\infty &= \infty \\
* e^{-\infty} &= 0 \\
* e^{\mathrm{NaN}} &= \mathrm{NaN} \\
* e^0 &= 1\ \mathrm{is\ exact\ for\ finite\ argument\ only}
* \end{align*}
* ```
*
* ## Notes
*
* - According to an error analysis, the error is always less than \\(1\\) ulp (unit in the last place).
*
* - For an IEEE double,
*
* - if \\(x > 7.09782712893383973096\mbox{e+}02\\), then \\(e^{x}\\) overflows
* - if \\(x < -7.45133219101941108420\mbox{e+}02\\), then \\(e^{x}\\) underflows
*
* - The hexadecimal values included in the source code are the intended ones for the used constants. Decimal values may be used, provided that the compiler will convert from decimal to binary accurately enough to produce the intended hexadecimal values.
*
*
* @param {number} x - input value
* @returns {number} function value
*
* @example
* var v = exp( 4.0 );
* // returns ~54.5982
*
* @example
* var v = exp( -9.0 );
* // returns ~1.234e-4
*
* @example
* var v = exp( 0.0 );
* // returns 1.0
*
* @example
* var v = exp( NaN );
* // returns NaN

/**
* Evaluates the natural logarithm of the gamma function.
*
* ## Method
*
* 1. Argument reduction for \\(0 < x \leq 8\\). Since \\(\Gamma(1+s) = s \Gamma(s)\\), for \\(x \in \[0,8]\\), we may reduce \\(x\\) to a number in \\(\[1.5,2.5]\\) by
*
* ```tex
* \operatorname{lgamma}(1+s) = \ln(s) + \operatorname{lgamma}(s)
* ```
*
* For example,
*
* ```tex
* \begin{align*}
* \operatorname{lgamma}(7.3) &= \ln(6.3) + \operatorname{lgamma}(6.3) \\
* &= \ln(6.3 \cdot 5.3) + \operatorname{lgamma}(5.3) \\
* &= \ln(6.3 \cdot 5.3 \cdot 4.3 \cdot 3.3 \cdot2.3) + \operatorname{lgamma}(2.3)
* \end{align*}
* ```
*
* 2. Compute a polynomial approximation of \\(\mathrm{lgamma}\\) around its minimum (\\(\mathrm{ymin} = 1.461632144968362245\\)) to maintain monotonicity. On the interval \\(\[\mathrm{ymin} - 0.23, \mathrm{ymin} + 0.27]\\) (i.e., \\(\[1.23164,1.73163]\\)), we let \\(z = x - \mathrm{ymin}\\) and use
*
* ```tex
* \operatorname{lgamma}(x) = -1.214862905358496078218 + z^2 \cdot \operatorname{poly}(z)
* ```
*
* where \\(\operatorname{poly}(z)\\) is a \\(14\\) degree polynomial.
*
* 3. Compute a rational approximation in the primary interval \\(\[2,3]\\). Let \\( s = x - 2.0 \\). We can thus use the approximation
*
* ```tex
* \operatorname{lgamma}(x) = \frac{s}{2} + s\frac{\operatorname{P}(s)}{\operatorname{Q}(s)}
* ```
*
* with accuracy
*
* ```tex
* \biggl|\frac{\mathrm{P}}{\mathrm{Q}} - \biggr(\operatorname{lgamma}(x)-\frac{s}{2}\biggl)\biggl| < 2^{-61.71}
* ```
*
* The algorithms are based on the observation
*
* ```tex
* \operatorname{lgamma}(2+s) = s(1 - \gamma) + \frac{\zeta(2) - 1}{2} s^2 - \frac{\zeta(3) - 1}{3} s^3 + \ldots
* ```
*
* where \\(\zeta\\) is the zeta function and \\(\gamma = 0.5772156649...\\) is the Euler-Mascheroni constant, which is very close to \\(0.5\\).
*
* 4. For \\(x \geq 8\\),
*
* ```tex
* \operatorname{lgamma}(x) \approx \biggl(x-\frac{1}{2}\biggr) \ln(x) - x + \frac{\ln(2\pi)}{2} + \frac{1}{12x} - \frac{1}{360x^3} + \ldots
* ```
*
* which can be expressed
*
* ```tex
* \operatorname{lgamma}(x) \approx \biggl(x-\frac{1}{2}\biggr)(\ln(x)-1)-\frac{\ln(2\pi)-1}{2} + \ldots
* ```
*
* Let \\(z = \frac{1}{x}\\). We can then use the approximation
*
* ```tex
* f(z) = \operatorname{lgamma}(x) - \biggl(x-\frac{1}{2}\biggr)(\ln(x)-1)
* ```
*
* by
*
* ```tex
* w = w_0 + w_1 z + w_2 z^3 + w_3 z^5 + \ldots + w_6 z^{11}
* ```
*
* where
*
* ```tex
* |w - f(z)| < 2^{-58.74}
* ```
*
* 5. For negative \\(x\\), since
*
* ```tex
* -x \Gamma(-x) \Gamma(x) = \frac{\pi}{\sin(\pi x)}
* ```
*
* where \\(\Gamma\\) is the gamma function, we have
*
* ```tex
* \Gamma(x) = \frac{\pi}{\sin(\pi x)(-x)\Gamma(-x)}
* ```
*
* Since \\(\Gamma(-x)\\) is positive,
*
* ```tex
* \operatorname{sign}(\Gamma(x)) = \operatorname{sign}(\sin(\pi x))
* ```
*
* for \\(x < 0\\). Hence, for \\(x < 0\\),
*
* ```tex
* \mathrm{signgam} = \operatorname{sign}(\sin(\pi x))
* ```
*
* and
*
* ```tex
* \begin{align*}
* \operatorname{lgamma}(x) &= \ln(|\Gamma(x)|) \\
* &= \ln\biggl(\frac{\pi}{|x \sin(\pi x)|}\biggr) - \operatorname{lgamma}(-x)
* \end{align*}
* ```
*
* <!-- <note> -->
*
* Note that one should avoid computing \\(\pi (-x)\\) directly in the computation of \\(\sin(\pi (-x))\\).
*
* <!-- </note> -->
*
*
* ## Special Cases
*
* ```tex
* \begin{align*}
* \operatorname{lgamma}(2+s) &\approx s (1-\gamma) & \mathrm{for\ tiny\ s} \\
* \operatorname{lgamma}(x) &\approx -\ln(x) & \mathrm{for\ tiny\ x} \\
* \operatorname{lgamma}(1) &= 0 & \\
* \operatorname{lgamma}(2) &= 0 & \\
* \operatorname{lgamma}(0) &= \infty & \\
* \operatorname{lgamma}(\infty) &= \infty & \\
* \operatorname{lgamma}(-\mathrm{integer}) &= \pm \infty
* \end{align*}

/**
* Computes the cosine on \\( \[-\pi/4, \pi/4] \\), where \\( \pi/4 \approx 0.785398164 \\).
*
* ## Method
*
* - Since \\( \cos(-x) = \cos(x) \\), we need only to consider positive \\(x\\).
*
* - If \\( x < 2^{-27} \\), return \\(1\\) which is inexact if \\( x \ne 0 \\).
*
* - \\( cos(x) \\) is approximated by a polynomial of degree \\(14\\) on \\( \[0,\pi/4] \\).
*
* ```tex
* \cos(x) \approx 1 - \frac{x \cdot x}{2} + C_1 \cdot x^4 + \ldots + C_6 \cdot x^{14}
* ```
*
* where the Remez error is
*
* ```tex
* \left| \cos(x) - \left( 1 - \frac{x^2}{2} + C_1x^4 + C_2x^6 + C_3x^8 + C_4x^{10} + C_5x^{12} + C_6x^{15} \right) \right| \le 2^{-58}
* ```
*
* - Let \\( C_1x^4 + C_2x^6 + C_3x^8 + C_4x^{10} + C_5x^{12} + C_6x^{14} \\), then
*
* ```tex
* \cos(x) \approx 1 - \frac{x \cdot x}{2} + r
* ```
*
* Since
*
* ```tex
* \cos(x+y) \approx \cos(x) - \sin(x) \cdot y \approx \cos(x) - x \cdot y
* ```
*
* a correction term is necessary in \\( \cos(x) \\). Hence,
*
* ```tex
* \cos(x+y) = 1 - \left( \frac{x \cdot x}{2} - (r - x \cdot y) \right)
* ```
*
* For better accuracy, rearrange to
*
* ```tex
* \cos(x+y) \approx w + \left( t + ( r - x \cdot y ) \right)
* ```
*
* where \\( w = 1 - \frac{x \cdot x}{2} \\) and \\( t \\) is a tiny correction term (\\( 1 - \frac{x \cdot x}{2} = w + t \\) exactly in infinite precision). The exactness of \\(w + t\\) in infinite precision depends on \\(w\\) and \\(t\\) having the same precision as \\(x\\).
*
*
* @param {number} x - input value (in radians, assumed to be bounded by ~pi/4 in magnitude)
* @param {number} y - tail of `x`
* @returns {number} cosine

* - \\( \sin(x) \\) is approximated by a polynomial of degree \\(13\\) on \\( \left\[0,\tfrac{pi}{4}\right] \\)
*
* ```tex
* \sin(x) \approx x + S_1 \cdot x^3 + \ldots + S_6 \cdot x^{13}
* ```
*
* where
*
* ```tex
* \left| \frac{\sin(x)}{x} \left( 1 + S_1 \cdot x + S_2 \cdot x + S_3 \cdot x + S_4 \cdot x + S_5 \cdot x + S_6 \cdot x \right) \right| \le 2^{-58}
* ```
*
* - We have
*
* ```tex
* \sin(x+y) = \sin(x) + \sin'(x') \cdot y \approx \sin(x) + (1-x*x/2) \cdot y
* ```
*
* For better accuracy, let
*
* ```tex
* r = x^3 * \left( S_2 + x^2 \cdot \left( S_3 + x^2 * \left( S_4 + x^2 \cdot ( S_5+x^2 \cdot S_6 ) \right) \right) \right)
* ```

/**
* Performs C-like multiplication of two unsigned 32-bit integers.
*
* ## Method
*
* - To emulate C-like multiplication without the aid of 64-bit integers, we recognize that a 32-bit integer can be split into two 16-bit words
*
* ```tex
* a = w_h*2^{16} + w_l
* ```
*
* where \\( w_h \\) is the most significant 16 bits and \\( w_l \\) is the least significant 16 bits. For example, consider the maximum unsigned 32-bit integer \\( 2^{32}-1 \\)
*
* ```binarystring
* 11111111111111111111111111111111
* ```
*
* The 16-bit high word is then
*
* ```binarystring
* 1111111111111111
* ```
*
* and the 16-bit low word
*
* ```binarystring
* 1111111111111111
* ```
*
* If we cast the high word to 32-bit precision and multiply by \\( 2^{16} \\) (equivalent to a 16-bit left shift), then the bit sequence is
*
* ```binarystring
* 11111111111111110000000000000000
* ```
*
* Similarly, upon casting the low word to 32-bit precision, the bit sequence is
*
* ```binarystring
* 00000000000000001111111111111111
* ```
*
* From the rules of binary addition, we recognize that adding the two 32-bit values for the high and low words will return our original value \\( 2^{32}-1 \\).
*
* - Accordingly, the multiplication of two 32-bit integers can be expressed
*
* ```tex
* \begin{align*}
* a \cdot b &= ( a_h \cdot 2^{16} + a_l) \cdot ( b_h \cdot 2^{16} + b_l) \\
* &= a_l \cdot b_l + a_h \cdot b_l \cdot 2^{16} + a_l \cdot b_h \cdot 2^{16} + (a_h \cdot b_h) \cdot 2^{32} \\
* &= a_l \cdot b_l + (a_h \cdot b_l + a_l \cdot b_h) \cdot 2^{16} + (a_h \cdot b_h) \cdot 2^{32}
* \end{align*}
* ```
*
* - We note that multiplying (dividing) an integer by \\( 2^n \\) is equivalent to performing a left (right) shift of \\( n \\) bits.
*
* - Further, as we want to return an integer of the same precision, for a 32-bit integer, the return value will be modulo \\( 2^{32} \\). Stated another way, we only care about the low word of a 64-bit result.
*
* - Accordingly, the last term, being evenly divisible by \\( 2^{32} \\), drops from the equation leaving the remaining two terms as the remainder.
*
* ```tex
* a \cdot b = a_l \cdot b_l + (a_h \cdot b_l + a_l \cdot b_h) << 16
* ```
*
* - Lastly, the second term in the above equation contributes to the middle bits and may cause the product to "overflow". However, we can disregard (`>>>0`) overflow bits due modulo arithmetic, as discussed earlier with regard to the term involving the partial product of high words.
*
*
* @param {uinteger32} a - integer
* @param {uinteger32} b - integer
* @returns {uinteger32} product
*
* @example
* var v = uimul( 10>>>0, 4>>>0 );
* // returns 40

/**
* Generates a pseudorandom integer on the interval \\( [1,2^{32}-1) \\).
*
* ## Method
*
* - When generating normalized double-precision floating-point numbers, we first generate two pseudorandom integers \\( x \\) and \\( y \\) on the interval \\( [1,2^{32}-1) \\) for a combined \\( 64 \\) random bits.
*
* - We would like \\( 53 \\) random bits to generate a 53-bit precision integer and, thus, want to discard \\( 11 \\) of the generated bits.
*
* - We do so by discarding \\( 5 \\) bits from \\( x \\) and \\( 6 \\) bits from \\( y \\).
*
* - Accordingly, \\( x \\) contains \\( 27 \\) random bits, which are subsequently shifted left \\( 26 \\) bits (multiplied by \\( 2^{26} \\), and \\( y \\) contains \\( 26 \\) random bits to fill in the lower \\( 26 \\) bits. When summed, they combine to comprise \\( 53 \\) random bits of a double-precision floating-point integer.
*
* - As an example, suppose, for the sake of argument, the 32-bit PRNG generates the maximum unsigned 32-bit integer \\( 2^{32}-1 \\) twice in a row. Then,
*
* ```javascript
* x = 4294967295 >>> 5; // 00000111111111111111111111111111
* y = 4294967295 >>> 6; // 00000011111111111111111111111111
* ```
*
* Multiplying \\( x \\) by \\( 2^{26} \\) returns \\( 9007199187632128 \\), which, in binary, is
*
* ```binarystring
* 0 10000110011 11111111111111111111 11111100000000000000000000000000
* ```
*
* Adding \\( y \\) yields \\( 9007199254740991 \\) (the maximum "safe" double-precision floating-point integer value), which, in binary, is
*
* ```binarystring
* 0 10000110011 11111111111111111111 11111111111111111111111111111111
* ```
*
* - Similarly, suppose the 32-bit PRNG generates the following values
*
* ```javascript
* x = 1 >>> 5; // 0 => 00000000000000000000000000000000
* y = 64 >>> 6; // 1 => 00000000000000000000000000000001
* ```
*
* Multiplying \\( x \\) by \\( 2^{26} \\) returns \\( 0 \\), which, in binary, is
*
* ```binarystring
* 0 00000000000 00000000000000000000 00000000000000000000000000000000
* ```
*
* Adding \\( y \\) yields \\( 1 \\), which, in binary, is
*
* ```binarystring
* 0 01111111111 00000000000000000000 00000000000000000000000000000000
* ```
*
* - As different combinations of \\( x \\) and \\( y \\) are generated, different combinations of double-precision floating-point exponent and significand bits will be toggled, thus generating pseudorandom double-precision floating-point numbers.

* Creates a string from a sequence of Unicode code points.

* ## Notes
*
* - UTF-16 encoding uses one 16-bit unit for non-surrogates (U+0000 to U+D7FF and U+E000 to U+FFFF).
* - UTF-16 encoding uses two 16-bit units (surrogate pairs) for U+10000 to U+10FFFF and encodes U+10000-U+10FFFF by subtracting 0x10000 from the code point, expressing the result as a 20-bit binary, and splitting the 20 bits of 0x0-0xFFFFF as upper and lower 10-bits. The respective 10-bits are stored in two 16-bit words: a high and a low surrogate.
*

* @throws {Error} must provide either an array-like object of code points or one or more code points as separate arguments

* - The function is greedy, disregarding the notion of a `level`. Instead, the function deep copies all properties, as we assume the concept of `level` applies only to the class instance reference but not to its internal state. This prevents, in theory, two instances from sharing state.

// a transform stream is a readable/writable stream where you do
// something with the data. Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored. (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation. For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes. When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up. When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer. When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks. If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk. However,
// a pathological inflate type of transform can cause excessive buffering
// here. For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output. In this case, you could write a very small
// amount of input, and end up with a very large amount of output. In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform. A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.

* A Stream-like function that manages the viewName state in the URL via the history API
* in order to facilitate tab switches without a full page load.
*
* Called with no arguments, this method returns the current view name; called with 1
* argument, it sets the new value as the current view (and forces the page to reflect
* that change).
*
* This API is built so that callers of this function need no knowledge of the current
* mithril route. The current route is preserved, and viewName can be independently set
* to make bookmarkable, stateful URLs.
*
* The differences from Stream are that 1) this really only works with String values
* and 2) one cannot use this in Stream.combine/merge/map because it cannot be registered
* as a dependency to another Stream.
*
* That said, it's worth noting that this *could* be equivalently implemented as a genuine
* Stream that is dependent on a vanilla Stream instance (by way of Sream.map or
* Stream.combine), but there's no practical benefit to this.
*
* Here's how it would look anyway:
*
* ```
* const viewName = Stream(queryObject().viewName);
* const currentView = viewName.map(function onUpdateValue(val) {
* // logic to build new URL and handle history, routing, etc
* // goes here.
