/**
* Controller for handling basic camera events on a Landmarker.
*
* A landmarker in general has complex state - what landmarks are selected,
* what mesh is being used, lighting arrangements, and so on. The camera's
* behavior however is simple - in response to certain mouse and touch
* interactions, the camera is rotated, zoomed, and panned around some sort of
* target. This class encapsulates this behavior.
*
* Takes a camera object as it's first parameter, and optionally a domElement to
* attach to (if none provided, the document is used).
*
* Hooks up the following callbacks to the domElement:
*
* - focus(target) // refocus the camera on a new target
* - pan(vector) // pan the camera along a certain vector
* - zoom(vector) // zoom the camera along a certain vector
* - rotate(delta) // rotate the camera around the target
*
* Note that other more complex behaviors (selecting and repositioning landmarks
* for instance) can disable the Controller temporarily with the enabled
* property.

* - 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.

/**
* Rounds a numeric value to the nearest multiple of \\(10^n\\) toward negative infinity.
*
* ## Method
*
* 1. If \\(|x| <= 2^{53}\\) and \\(|n| <= 308\\), we can use the formula
*
* ```tex
* \operatorname{floorn}(x,n) = \frac{\operatorname{floor}(x \cdot 10^{-n})}{10^{-n}}
* ```
*
* which shifts the decimal to the nearest multiple of \\(10^n\\), performs a standard \\(\mathrm{floor}\\) operation, and then shifts the decimal to its original position.
*
* <!-- <note> -->
*
* If \\(x \cdot 10^{-n}\\) overflows, \\(x\\) lacks a sufficient number of decimal digits to have any effect when rounding. Accordingly, the rounded value is \\(x\\).
*
* <!-- </note> -->
*
* <!-- <note> -->
*
* Note that rescaling \\(x\\) can result in unexpected behavior. For instance, the result of \\(\operatorname{floorn}(-0.2-0.1,-16)\\) is \\(-0.3000000000000001\\) and not \\(-0.3\\). While possibly unexpected, this is not a bug. The behavior stems from the fact that most decimal fractions cannot be exactly represented as floating-point numbers. And further, rescaling can lead to slightly different fractional values, which, in turn, affects the result of \\(\mathrm{floor}\\).
*
* <!-- </note> -->
*
* 2. If \\(n > 308\\), we recognize that the maximum absolute double-precision floating-point number is \\(\approx 1.8\mbox{e}308\\) and, thus, the result of rounding any possible negative finite number \\(x\\) to the nearest \\(10^n\\) is \\(-\infty\\) and any possible positive finite number \\(x\\) is \\(+0\\). To ensure consistent behavior with \\(\operatorname{floor}(x)\\), if \\(x > 0\\), the sign of \\(x\\) is preserved.
*
* 3. If \\(n < -324\\), \\(n\\) exceeds the maximum number of possible decimal places (such as with subnormal numbers), and, thus, the rounded value is \\(x\\).
*
* 4. If \\(x > 2^{53}\\), \\(x\\) is **always** an integer (i.e., \\(x\\) has no decimal digits). If \\(n <= 0\\), the rounded value is \\(x\\).
*
* 5. If \\(n < -308\\), we let \\(m = n + 308\\) and modify the above formula to avoid overflow.
*
* ```tex
* \operatorname{floorn}(x,n) = \frac{\biggl(\frac{\operatorname{floor}( (x \cdot 10^{308}) 10^{-m})}{10^{308}}\biggr)}{10^{-m}}
* ```
*
* If overflow occurs, the rounded value is \\(x\\).
*
*
* ## Special Cases
*
* ```tex
* \begin{align*}
* \operatorname{floorn}(\mathrm{NaN}, n) &= \mathrm{NaN} \\
* \operatorname{floorn}(x, \mathrm{NaN}) &= \mathrm{NaN} \\
* \operatorname{floorn}(x, \pm\infty) &= \mathrm{NaN} \\
* \operatorname{floorn}(\pm\infty, n) &= \pm\infty \\
* \operatorname{floorn}(\pm 0, n) &= \pm 0
* \end{align*}
* ```
*
*
* @param {number} x - input value
* @param {integer} n - integer power of 10
* @returns {number} rounded value
*
* @example
* // Round a value to 4 decimal places:
* var v = floorn( 3.141592653589793, -4 );
* // returns 3.1415
*
* @example
* // If n = 0, `floorn` behaves like `floor`:
* var v = floorn( 3.141592653589793, 0 );
* // returns 3.0
*
* @example
* // Round a value to the nearest thousand:
* var v = floorn( 12368.0, 3 );
* // returns 12000.0

/**
* 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.

/**
* 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

// 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.

Server allows you to host "experts" - pytorch sub-networks used by Decentralized Mixture of Experts.
After creation, a server should be started: see Server.run or Server.run_in_background.
A working server does 3 things:
- processes incoming forward/backward requests via Runtime (created by the server)
- publishes updates to expert status every :update_period: seconds
- follows orders from HivemindController - if it exists
:type dht: DHT or None. Server with dht=None will NOT be visible from DHT,
but it will still support accessing experts directly with RemoteExpert(uid=UID, endpoint="IPADDR:PORT").
:param expert_backends: dict{expert uid (str) : ExpertBackend} for all expert hosted by this server.
:param listen_on: server's dht address that determines how it can be accessed. Address and (optional) port
:param num_connection_handlers: maximum number of simultaneous requests. Please note that the default value of 1
if too small for normal functioning, we recommend 4 handlers per expert backend.
:param update_period: how often will server attempt to publish its state (i.e. experts) to the DHT;
if dht is None, this parameter is ignored.
