      * @param {object} options An options object, with the following properties:
      *
      *    - `controller` - `{(string=|function()=}` Controller fn that should be associated with
      *      newly created scope or the name of a registered controller if passed as a string.
      *    - `controllerAs` - `{string=}` A controller alias name. If present the controller will be
      *      published to scope under the `controllerAs` name.
      *    - `template` - `{string=}` An html template as a string.
      *    - `templateUrl` - `{string=}` A path to an html template.
      *    - `transformTemplate` - `{function(template)=}` A function which transforms the template after
      *      it is loaded. It will be given the template string as a parameter, and should
      *      return a a new string representing the transformed template.
      *    - `resolve` - `{Object.<string, function>=}` - An optional map of dependencies which should
      *      be injected into the controller. If any of these dependencies are promises, the compiler
      *      will wait for them all to be resolved, or if one is rejected before the controller is
      *      instantiated `compile()` will fail..
      *      * `key` - `{string}`: a name of a dependency to be injected into the controller.
      *      * `factory` - `{string|function}`: If `string` then it is an alias for a service.
      *        Otherwise if function, then it is injected and the return value is treated as the
      *        dependency. If the result is a promise, it is resolved before its value is 
      *        injected into the controller.
      *
      * @returns {object=} promise A promise, which will be resolved with a `compileData` object.
      * `compileData` has the following properties: 
      *
      *   - `element` - `{element}`: an uncompiled element matching the provided template.
      *   - `link` - `{function(scope)}`: A link function, which, when called, will compile
      *     the element and instantiate the provided controller (if given).
      *   - `locals` - `{object}`: The locals which will be passed into the controller once `link` is
      *     called. If `bindToController` is true, they will be coppied to the ctrl instead
      *   - `bindToController` - `bool`: bind the locals to the controller, instead of passing them in.

  /* Some Example Valid Theming Expressions
   * =======================================
   *
   * Intention group expansion: (valid for primary, accent, warn, background)
   *
   * {{primary-100}} - grab shade 100 from the primary palette
   * {{primary-100-0.7}} - grab shade 100, apply opacity of 0.7
   * {{primary-100-contrast}} - grab shade 100's contrast color
   * {{primary-hue-1}} - grab the shade assigned to hue-1 from the primary palette
   * {{primary-hue-1-0.7}} - apply 0.7 opacity to primary-hue-1
   * {{primary-color}} - Generates .md-hue-1, .md-hue-2, .md-hue-3 with configured shades set for each hue
   * {{primary-color-0.7}} - Apply 0.7 opacity to each of the above rules
   * {{primary-contrast}} - Generates .md-hue-1, .md-hue-2, .md-hue-3 with configured contrast (ie. text) color shades set for each hue
   * {{primary-contrast-0.7}} - Apply 0.7 opacity to each of the above rules
   *
   * Foreground expansion: Applies rgba to black/white foreground text
   *
   * {{foreground-1}} - used for primary text
   * {{foreground-2}} - used for secondary text/divider
   * {{foreground-3}} - used for disabled text
   * {{foreground-4}} - used for dividers

   *
   *   - `templateUrl` - `{string=}`: The url of an html template file that will
   *   be used as the content of the bottom sheet. Restrictions: the template must
   *   have an outer `md-bottom-sheet` element.
   *   - `template` - `{string=}`: Same as templateUrl, except this is an actual
   *   template string.
   *   - `scope` - `{object=}`: the scope to link the template / controller to. If none is specified, it will create a new child scope.
   *     This scope will be destroyed when the bottom sheet is removed unless `preserveScope` is set to true.
   *   - `preserveScope` - `{boolean=}`: whether to preserve the scope when the element is removed. Default is false
   *   - `controller` - `{string=}`: The controller to associate with this bottom sheet.
   *   - `locals` - `{string=}`: An object containing key/value pairs. The keys will
   *   be used as names of values to inject into the controller. For example,
   *   `locals: {three: 3}` would inject `three` into the controller with the value
   *   of 3.
   *   - `targetEvent` - `{DOMClickEvent=}`: A click's event object. When passed in as an option,
   *   the location of the click will be used as the starting point for the opening animation
   *   of the the dialog.
   *   - `resolve` - `{object=}`: Similar to locals, except it takes promises as values
   *   and the bottom sheet will not open until the promises resolve.
   *   - `controllerAs` - `{string=}`: An alias to assign the controller to on the scope.
   *   - `parent` - `{element=}`: The element to append the bottom sheet to. The `parent` may be a `function`, `string`,
   *   `object`, or null. Defaults to appending to the body of the root element (or the root element) of the application.
   *   e.g. angular.element(document.getElementById('content')) or "#content"
   *   - `disableParentScroll` - `{boolean=}`: Whether to disable scrolling while the bottom sheet is open.
   *     Default true.

   *
   * @description
   * `$mdDialog` opens a dialog over the app to inform users about critical information or require
   *  them to make decisions. There are two approaches for setup: a simple promise API
   *  and regular object syntax.
   *
   * ## Restrictions
   *
   * - The dialog is always given an isolate scope.
   * - The dialog's template must have an outer `<md-dialog>` element.
   *   Inside, use an `<md-dialog-content>` element for the dialog's content, and use
   *   an element with class `md-actions` for the dialog's actions.
   * - Dialogs must cover the entire application to keep interactions inside of them.
   * Use the `parent` option to change where dialogs are appended.
   *
   * ## Sizing
   * - Complex dialogs can be sized with `flex="percentage"`, i.e. `flex="66"`.
   * - Default max-width is 80% of the `rootElement` or `parent`.

   * @param {object} optionsOrPreset Either provide an `$mdDialogPreset` returned from `alert()`, and
   * `confirm()`, or an options object with the following properties:
   *   - `templateUrl` - `{string=}`: The url of a template that will be used as the content
   *   of the dialog.
   *   - `template` - `{string=}`: Same as templateUrl, except this is an actual template string.
   *   - `targetEvent` - `{DOMClickEvent=}`: A click's event object. When passed in as an option,
   *     the location of the click will be used as the starting point for the opening animation
   *     of the the dialog.
   *   - `scope` - `{object=}`: the scope to link the template / controller to. If none is specified,
   *     it will create a new isolate scope.
   *     This scope will be destroyed when the dialog is removed unless `preserveScope` is set to true.
   *   - `preserveScope` - `{boolean=}`: whether to preserve the scope when the element is removed. Default is false
   *   - `disableParentScroll` - `{boolean=}`: Whether to disable scrolling while the dialog is open.
   *     Default true.
   *   - `hasBackdrop` - `{boolean=}`: Whether there should be an opaque backdrop behind the dialog.
   *     Default true.
   *   - `clickOutsideToClose` - `{boolean=}`: Whether the user can click outside the dialog to
   *     close it. Default false.
   *   - `escapeToClose` - `{boolean=}`: Whether the user can press escape to close the dialog.
   *     Default true.
   *   - `focusOnOpen` - `{boolean=}`: An option to override focus behavior on open. Only disable if
   *     focusing some other way, as focus management is required for dialogs to be accessible.
   *     Defaults to true.
   *   - `controller` - `{string=}`: The controller to associate with the dialog. The controller
   *     will be injected with the local `$mdDialog`, which passes along a scope for the dialog.
   *   - `locals` - `{object=}`: An object containing key/value pairs. The keys will be used as names
   *     of values to inject into the controller. For example, `locals: {three: 3}` would inject
   *     `three` into the controller, with the value 3. If `bindToController` is true, they will be
   *     copied to the controller instead.
   *   - `bindToController` - `bool`: bind the locals to the controller, instead of passing them in.
   *     These values will not be available until after initialization.
   *   - `resolve` - `{object=}`: Similar to locals, except it takes promises as values, and the
   *     dialog will not open until all of the promises resolve.
   *   - `controllerAs` - `{string=}`: An alias to assign the controller to on the scope.
   *   - `parent` - `{element=}`: The element to append the dialog to. Defaults to appending
   *     to the root element of the application.
   *   - `onComplete` `{function=}`: Callback function used to announce when the show() action is
   *     finished.
   *   - `onRemoving` `{function=} Callback function used to announce the close/hide() action is
   *     starting. This allows developers to run custom animations in parallel the close animations.

     * @description
     * The `<md-fab-speed-dial>` directive is used to present a series of popup elements (usually
     * `<md-button>`s) for quick access to common actions.
     *
     * There are currently two animations available by applying one of the following classes to
     * the component:
     *
     *  - `md-fling` - The speed dial items appear from underneath the trigger and move into their
     *    appropriate positions.
     *  - `md-scale` - The speed dial items appear in their proper places by scaling from 0% to 100%.
     *
     * You may also easily position the trigger by applying one one of the following classes to the
     * `<md-fab-speed-dial>` element:
     *  - `md-fab-top-left`
     *  - `md-fab-top-right`
     *  - `md-fab-bottom-left`
     *  - `md-fab-bottom-right`
     *
     * These CSS classes use `position: absolute`, so you need to ensure that the container element
     * also uses `position: absolute` or `position: relative` in order for them to work.
     *
     * @usage
     * <hljs lang="html">

     * The `<md-fab-toolbar>` directive is used present a toolbar of elements (usually `<md-button>`s)
     * for quick access to common actions when a floating action button is activated (via click or
     * keyboard navigation).
     *
     * You may also easily position the trigger by applying one one of the following classes to the
     * `<md-fab-toolbar>` element:
     *  - `md-fab-top-left`
     *  - `md-fab-top-right`
     *  - `md-fab-bottom-left`
     *  - `md-fab-bottom-right`
     *
     * These CSS classes use `position: absolute`, so you need to ensure that the container element
     * also uses `position: absolute` or `position: relative` in order for them to work.
     *

   * @description
   * Grid lists are an alternative to standard list views. Grid lists are distinct
   * from grids used for layouts and other visual presentations.
   *
   * A grid list is best suited to presenting a homogenous data type, typically
   * images, and is optimized for visual comprehension and differentiating between
   * like data types.
   *
   * A grid list is a continuous element consisting of tessellated, regular
   * subdivisions called cells that contain tiles (`md-grid-tile`).

   *    style="width: 300px; height: auto;" alt="Grid concepts legend">
   *
   * Cells are arrayed vertically and horizontally within the grid.
   *
   * Tiles hold content and can span one or more cells vertically or horizontally.
   *
   * ### Responsive Attributes
   *
   * The `md-grid-list` directive supports "responsive" attributes, which allow
   * different `md-cols`, `md-gutter` and `md-row-height` values depending on the
   * currently matching media query (as defined in `$mdConstant.MEDIA`).
   *
   * In order to set a responsive attribute, first define the fallback value with
   * the standard attribute name, then add additional attributes with the
   * following convention: `{base-attribute-name}-{media-query-name}="{value}"`
   * (ie. `md-cols-lg="8"`)
   *
   * @param {number} md-cols Number of columns in the grid.
   * @param {string} md-row-height One of
   * <ul>
   *   <li>CSS length - Fixed height rows (eg. `8px` or `1rem`)</li>
   *   <li>`{width}:{height}` - Ratio of width to height (eg.
   *   `md-row-height="16:9"`)</li>
   *   <li>`"fit"` - Height will be determined by subdividing the available
   *   height by the number of rows</li>
   * </ul>
   * @param {string=} md-gutter The amount of space between tiles in CSS units
   *     (default 1px)
   * @param {expression=} md-on-layout Expression to evaluate after layout. Event
   *     object is available as `$event`, and contains performance information.
   *
   * @usage
   * Basic:
   * <hljs lang="html">
   * <md-grid-list md-cols="5" md-gutter="1em" md-row-height="4:3">
   *   <md-grid-tile></md-grid-tile>
   * </md-grid-list>
   * </hljs>
   *
   * Fixed-height rows:
   * <hljs lang="html">
   * <md-grid-list md-cols="4" md-row-height="200px" ...>
   *   <md-grid-tile></md-grid-tile>
   * </md-grid-list>
   * </hljs>
   *
   * Fit rows:
   * <hljs lang="html">
   * <md-grid-list md-cols="4" md-row-height="fit" style="height: 400px;" ...>
   *   <md-grid-tile></md-grid-tile>
   * </md-grid-list>
   * </hljs>
   *
   * Using responsive attributes:
   * <hljs lang="html">
   * <md-grid-list
   *     md-cols-sm="2"
   *     md-cols-md="4"
   *     md-cols-lg="8"
   *     md-cols-gt-lg="12"
   *     ...>

   * @description
   * Use the `<input>` or the  `<textarea>` as a child of an `<md-input-container>`.
   *
   * @param {number=} md-maxlength The maximum number of characters allowed in this input. If this is
   *   specified, a character counter will be shown underneath the input.<br/><br/>
   *   The purpose of **`md-maxlength`** is exactly to show the max length counter text. If you don't
   *   want the counter text and only need "plain" validation, you can use the "simple" `ng-maxlength`
   *   or maxlength attributes.
   * @param {string=} aria-label Aria-label is required when no label is present.  A warning message
   *   will be logged in the console if not present.
   * @param {string=} placeholder An alternative approach to using aria-label when the label is not
   *   PRESENT. The placeholder text is copied to the aria-label attribute.
   * @param md-no-autogrow {boolean=} When present, textareas will not grow automatically.

   * is focusable, and by default the `<md-radio-button>`s are not.

   * The `<md-slider>` component allows the user to choose from a range of
   * values.
   *
   * As per the [material design spec](http://www.google.com/design/spec/style/color.html#color-ui-color-application)
   * the slider is in the accent color by default. The primary color palette may be used with
   * the `md-primary` class.
   *
   * It has two modes: 'normal' mode, where the user slides between a wide range
   * of values, and 'discrete' mode, where the user slides between only a few
   * select values.
   *
   * To enable discrete mode, add the `md-discrete` attribute to a slider,
   * and use the `step` attribute to change the distance between
   * values the user is allowed to pick.
   *
   * @usage
   * <h4>Normal Mode</h4>
   * <hljs lang="html">
   * <md-slider ng-model="myValue" min="5" max="500">
   * </md-slider>
   * </hljs>
   * <h4>Discrete Mode</h4>
   * <hljs lang="html">
   * <md-slider md-discrete ng-model="myDiscreteValue" step="10" min="10" max="130">
   * </md-slider>
   * </hljs>
   *
   * @param {boolean=} md-discrete Whether to enable discrete mode.
   * @param {number=} step The distance between values the user is allowed to pick. Default 1.

   * and `build()`, or an options object with the following properties:
   *
   *   - `templateUrl` - `{string=}`: The url of an html template file that will
   *     be used as the content of the toast. Restrictions: the template must
   *     have an outer `md-toast` element.
   *   - `template` - `{string=}`: Same as templateUrl, except this is an actual
   *     template string.
   *   - `scope` - `{object=}`: the scope to link the template / controller to. If none is specified, it will create a new child scope.
   *     This scope will be destroyed when the toast is removed unless `preserveScope` is set to true.
   *   - `preserveScope` - `{boolean=}`: whether to preserve the scope when the element is removed. Default is false
   *   - `hideDelay` - `{number=}`: How many milliseconds the toast should stay
   *     active before automatically closing.  Set to 0 or false to have the toast stay open until
   *     closed manually. Default: 3000.
   *   - `position` - `{string=}`: Where to place the toast. Available: any combination
   *     of 'bottom', 'left', 'top', 'right', 'fit'. Default: 'bottom left'.
   *   - `controller` - `{string=}`: The controller to associate with this toast.
   *     The controller will be injected the local `$mdToast.hide( )`, which is a function
   *     used to hide the toast.
   *   - `locals` - `{string=}`: An object containing key/value pairs. The keys will
   *     be used as names of values to inject into the controller. For example,
   *     `locals: {three: 3}` would inject `three` into the controller with the value
   *     of 3.
   *   - `bindToController` - `bool`: bind the locals to the controller, instead of passing them in. These values will not be available until after initialization.
   *   - `resolve` - `{object=}`: Similar to locals, except it takes promises as values
   *     and the toast will not open until the promises resolve.
   *   - `controllerAs` - `{string=}`: An alias to assign the controller to on the scope.
   *   - `parent` - `{element=}`: The element to append the toast to. Defaults to appending
   *     to the root element of the application.
   *
   * @returns {promise} A promise that can be resolved with `$mdToast.hide()` or
   * rejected with `$mdToast.cancel()`. `$mdToast.hide()` will resolve either with a Boolean
   * value == 'true' or the value passed as an argument to `$mdToast.hide()`.
   * And `$mdToast.cancel()` will resolve the promise with a Boolean value == 'false'

  /**
   * @ngdoc directive
   * @name mdAutocomplete
   * @module material.components.autocomplete
   *
   * @description
   * `<md-autocomplete>` is a special input component with a drop-down of all possible matches to a
   *     custom query. This component allows you to provide real-time suggestions as the user types
   *     in the input area.
   *
   * To start, you will need to specify the required parameters and provide a template for your
   *     results. The content inside `md-autocomplete` will be treated as a template.
   *
   * In more complex cases, you may want to include other content such as a message to display when
   *     no matches were found.  You can do this by wrapping your template in `md-item-template` and
   *     adding a tag for `md-not-found`.  An example of this is shown below.
   *
   * ### Validation
   *
   * You can use `ng-messages` to include validation the same way that you would normally validate;
   *     however, if you want to replicate a standard input with a floating label, you will have to
   *     do the following:
   *
   * - Make sure that your template is wrapped in `md-item-template`
   * - Add your `ng-messages` code inside of `md-autocomplete`
   * - Add your validation properties to `md-autocomplete` (ie. `required`)
   * - Add a `name` to `md-autocomplete` (to be used on the generated `input`)
   *
   * There is an example below of how this should look.
   *
   *
   * @param {expression} md-items An expression in the format of `item in items` to iterate over
   *     matches for your search.
   * @param {expression=} md-selected-item-change An expression to be run each time a new item is
   *     selected
   * @param {expression=} md-search-text-change An expression to be run each time the search text
   *     updates
   * @param {string=} md-search-text A model to bind the search query text to
   * @param {object=} md-selected-item A model to bind the selected item to
   * @param {string=} md-item-text An expression that will convert your object to a single string.
   * @param {string=} placeholder Placeholder text that will be forwarded to the input.
   * @param {boolean=} md-no-cache Disables the internal caching that happens in autocomplete
   * @param {boolean=} ng-disabled Determines whether or not to disable the input field
   * @param {number=} md-min-length Specifies the minimum length of text before autocomplete will
   *     make suggestions
   * @param {number=} md-delay Specifies the amount of time (in milliseconds) to wait before looking
   *     for results
   * @param {boolean=} md-autofocus If true, will immediately focus the input element
   * @param {boolean=} md-autoselect If true, the first item will be selected by default
   * @param {string=} md-menu-class This will be applied to the dropdown menu for styling
   * @param {string=} md-floating-label This will add a floating label to autocomplete and wrap it in
   *     `md-input-container`
   * @param {string=} md-input-name The name attribute given to the input element to be used with
   *     FormController
   * @param {string=} md-input-id An ID to be added to the input element
   * @param {number=} md-input-minlength The minimum length for the input's value for validation
   * @param {number=} md-input-maxlength The maximum length for the input's value for validation
   * @param {boolean=} md-select-on-match When set, autocomplete will automatically select exact
   *     the item if the search text is an exact match
   *
   * @usage
   * ###Basic Example
   * <hljs lang="html">
   *   <md-autocomplete
   *       md-selected-item="selectedItem"
   *       md-search-text="searchText"
   *       md-items="item in getMatches(searchText)"
   *       md-item-text="item.display">
   *     <span md-highlight-text="searchText">{{item.display}}</span>
   *   </md-autocomplete>
   * </hljs>
   *
   * ###Example with "not found" message
   * <hljs lang="html">
   * <md-autocomplete
   *     md-selected-item="selectedItem"
   *     md-search-text="searchText"
   *     md-items="item in getMatches(searchText)"
   *     md-item-text="item.display">
   *   <md-item-template>
   *     <span md-highlight-text="searchText">{{item.display}}</span>
   *   </md-item-template>

     * @description
     * `<md-chips>` is an input component for building lists of strings or objects. The list items are
     * displayed as 'chips'. This component can make use of an `<input>` element or an
     * `<md-autocomplete>` element.
     *
     * <strong>Custom `<md-chip-template>` template</strong>
     * A custom template may be provided to render the content of each chip. This is achieved by
     * specifying an `<md-chip-template>` element as a child of `<md-chips>`. Note: Any attributes on
     * `<md-chip-template>` will be dropped as only the innerHTML is used for the chip template. The
     * variables `$chip` and `$index` are available in the scope of `<md-chip-template>`, representing
     * the chip object and its index in the list of chips, respectively.
     * To override the chip delete control, include an element (ideally a button) with the attribute
     * `md-chip-remove`. A click listener to remove the chip will be added automatically. The element
     * is also placed as a sibling to the chip content (on which there are also click listeners) to
     * avoid a nested ng-click situation.

  /**
   * @ngdoc directive
   * @name mdIcon
   * @module material.components.icon
   *
   * @restrict E
   *
   * @description
   * The `md-icon` directive makes it easier to use vector-based icons in your app (as opposed to
   * raster-based icons types like PNG). The directive supports both icon fonts and SVG icons.
   *
   * Icons should be consider view-only elements that should not be used directly as buttons; instead nest a `<md-icon>`
   * inside a `md-button` to add hover and click features.
   *
   * ### Icon fonts
   * Icon fonts are a technique in which you use a font where the glyphs in the font are
   * your icons instead of text. Benefits include a straightforward way to bundle everything into a
   * single HTTP request, simple scaling, easy color changing, and more.
   *
   * `md-icon` let's you consume an icon font by letting you reference specific icons in that font
   * by name rather than character code.
   *
   * ### SVG
   * For SVGs, the problem with using `<img>` or a CSS `background-image` is that you can't take
   * advantage of some SVG features, such as styling specific parts of the icon with CSS or SVG
   * animation.
   *
   * `md-icon` makes it easier to use SVG icons by *inlining* the SVG into an `<svg>` element in the
   * document. The most straightforward way of referencing an SVG icon is via URL, just like a
   * traditional `<img>`. `$mdIconProvider`, as a convenience, let's you _name_ an icon so you can
   * reference it by name instead of URL throughout your templates.
   *
   * Additionally, you may not want to make separate HTTP requests for every icon, so you can bundle
   * your SVG icons together and pre-load them with $mdIconProvider as an icon set. An icon set can
   * also be given a name, which acts as a namespace for individual icons, so you can reference them
   * like `"social:cake"`.
   *
   * When using SVGs, both external SVGs (via URLs) or sets of SVGs [from icon sets] can be
   * easily loaded and used.When use font-icons, developers must following three (3) simple steps:
   *
   * <ol>
   * <li>Load the font library. e.g.<br/>
   *    &lt;link href="https://fonts.googleapis.com/icon?family=Material+Icons"
   *    rel="stylesheet"&gt;
   * </li>
   * <li> Use either (a) font-icon class names or (b) font ligatures to render the font glyph by using its textual name</li>
   * <li> Use &lt;md-icon md-font-icon="classname" /&gt; or <br/>
   *     use &lt;md-icon md-font-set="font library classname or alias"&gt; textual_name &lt;/md-icon&gt; or <br/>
   *     use &lt;md-icon md-font-set="font library classname or alias"&gt; numerical_character_reference &lt;/md-icon&gt;
   * </li>
   * </ol>
   *
   * Full details for these steps can be found:
   *
   * <ul>
   * <li>http://google.github.io/material-design-icons/</li>
   * <li>http://google.github.io/material-design-icons/#icon-font-for-the-web</li>
   * </ul>

   * The Material Design icon style <code>.material-icons</code> and the icon font references are published in
   * Material Design Icons:

   * <h2 id="material_design_icons">Material Design Icons</h2>
   * Using the Material Design Icon-Selector, developers can easily and quickly search for a Material Design font-icon and
   * determine its textual name and character reference code. Click on any icon to see the slide-up information
   * panel with details regarding a SVG download or information on the font-icon usage.

   * the class for the font-icon ligature. This value may also be an alias that is used to lookup the classname;
   * internally use `$mdIconProvider.fontSet(<alias>)` to determine the style name.

   *     external SVG.

   *     interpolated strings or expressions may also be used. Specific set names can be used with
   *     the syntax `<set name>:<icon name>`.<br/><br/>
   * To use icon sets, developers are required to pre-register the sets using the `$mdIconProvider` service.
   * @param {string=} aria-label Labels icon for accessibility. If an empty string is provided, icon
   * will be hidden from accessibility layer with `aria-hidden="true"`. If there's no aria-label on the icon
   * nor a label on the parent element, a warning will be logged to the console.
   * @param {string=} alt Labels icon for accessibility. If an empty string is provided, icon
   * will be hidden from accessibility layer with `aria-hidden="true"`. If there's no alt on the icon

   * ## Menu Bar Controls
   *
   * You may place `md-menu-items` that function as controls within menu bars.
   * There are two modes that are exposed via the `type` attribute of the `md-menu-item`.
   * `type="checkbox"` will function as a boolean control for the `ng-model` attribute of the
   * `md-menu-item`. `type="radio"` will function like a radio button, setting the `ngModel`
   * to the `string` value of the `value` attribute. If you need non-string values, you can use
   * `ng-value` to provide an expression (this is similar to how angular's native `input[type=radio]` works.
   *
   * <hljs lang="html">
   * <md-menu-bar>
   *  <md-menu>
   *    <button ng-click="$mdOpenMenu()">
   *      Sample Menu
   *    </button>
   *    <md-menu-content>
   *      <md-menu-item type="checkbox" ng-model="settings.allowChanges">Allow changes</md-menu-item>
   *      <md-menu-divider></md-menu-divider>
   *      <md-menu-item type="radio" ng-model="settings.mode" ng-value="1">Mode 1</md-menu-item>
   *      <md-menu-item type="radio" ng-model="settings.mode" ng-value="1">Mode 2</md-menu-item>
   *      <md-menu-item type="radio" ng-model="settings.mode" ng-value="1">Mode 3</md-menu-item>
   *    </md-menu-content>
   *  </md-menu>
   * </md-menu-bar>
   * </hljs>
   *
   *
   * ### Nesting Menus
   *
   * Menus may be nested within menu bars. This is commonly called cascading menus.
   * To nest a menu place the nested menu inside the content of the `md-menu-item`.
   * <hljs lang="html">
   * <md-menu-item>
   *   <md-menu>
   *     <button ng-click="$mdOpenMenu()">New</md-button>
   *     <md-menu-content>
   *       <md-menu-item><md-button ng-click="ctrl.sampleAction('New Document', $event)">Document</md-button></md-menu-item>
   *       <md-menu-item><md-button ng-click="ctrl.sampleAction('New Spreadsheet', $event)">Spreadsheet</md-button></md-menu-item>
   *       <md-menu-item><md-button ng-click="ctrl.sampleAction('New Presentation', $event)">Presentation</md-button></md-menu-item>
   *       <md-menu-item><md-button ng-click="ctrl.sampleAction('New Form', $event)">Form</md-button></md-menu-item>

  /**
   * @ngdoc directive

   * @module material.components.menu

   * @description
   *
   * Menus are elements that open when clicked. They are useful for displaying
   * additional options within the context of an action.
   *
   * Every `md-menu` must specify exactly two child elements. The first element is what is
   * left in the DOM and is used to open the menu. This element is called the trigger element.
   * The trigger element's scope has access to `$mdOpenMenu($event)`
   * which it may call to open the menu. By passing $event as argument, the
   * corresponding event is stopped from propagating up the DOM-tree.
   *
   * The second element is the `md-menu-content` element which represents the
   * contents of the menu when it is open. Typically this will contain `md-menu-item`s,
   * but you can do custom content as well.
   *
   * <hljs lang="html">
   * <md-menu>
   *  <!-- Trigger element is a md-button with an icon -->
   *  <md-button ng-click="$mdOpenMenu($event)" class="md-icon-button" aria-label="Open sample menu">
   *    <md-icon md-svg-icon="call:phone"></md-icon>
   *  </md-button>
   *  <md-menu-content>
   *    <md-menu-item><md-button ng-click="doSomething()">Do Something</md-button></md-menu-item>
   *  </md-menu-content>
   * </md-menu>
   * </hljs>
  
   * ## Sizing Menus
   *
   * The width of the menu when it is open may be specified by specifying a `width`
   * attribute on the `md-menu-content` element.
   * See the [Material Design Spec](http://www.google.com/design/spec/components/menus.html#menus-specs)
   * for more information.
   *
   *
   * ## Aligning Menus
   *
   * When a menu opens, it is important that the content aligns with the trigger element.
   * Failure to align menus can result in jarring experiences for users as content
   * suddenly shifts. To help with this, `md-menu` provides serveral APIs to help
   * with alignment.
   *
   * ### Target Mode
   *
   * By default, `md-menu` will attempt to align the `md-menu-content` by aligning
   * designated child elements in both the trigger and the menu content.
   *
   * To specify the alignment element in the `trigger` you can use the `md-menu-origin`
   * attribute on a child element. If no `md-menu-origin` is specified, the `md-menu`
   * will be used as the origin element.
   *
   * Similarly, the `md-menu-content` may specify a `md-menu-align-target` for a
   * `md-menu-item` to specify the node that it should try and align with.
   *
   * In this example code, we specify an icon to be our origin element, and an
   * icon in our menu content to be our alignment target. This ensures that both
   * icons are aligned when the menu opens.
   *
   * <hljs lang="html">
   * <md-menu>
   *  <md-button ng-click="$mdOpenMenu($event)" class="md-icon-button" aria-label="Open some menu">
   *    <md-icon md-menu-origin md-svg-icon="call:phone"></md-icon>
   *  </md-button>
   *  <md-menu-content>
   *    <md-menu-item>
   *      <md-button ng-click="doSomething()" aria-label="Do something">
   *        <md-icon md-menu-align-target md-svg-icon="call:phone"></md-icon>
   *        Do Something
   *      </md-button>
   *    </md-menu-item>
   *  </md-menu-content>
   * </md-menu>
   * </hljs>
   *
   * Sometimes we want to specify alignment on the right side of an element, for example
   * if we have a menu on the right side a toolbar, we want to right align our menu content.
   *
   * We can specify the origin by using the `md-position-mode` attribute on both
   * the `x` and `y` axis. Right now only the `x-axis` has more than one option.
   * You may specify the default mode of `target target` or
   * `target-right target` to specify a right-oriented alignment target. See the
   * position section of the demos for more examples.
   *
   * ### Menu Offsets
   *
   * It is sometimes unavoidable to need to have a deeper level of control for
   * the positioning of a menu to ensure perfect alignment. `md-menu` provides
   * the `md-offset` attribute to allow pixel level specificty of adjusting the
   * exact positioning.
   *
   * This offset is provided in the format of `x y` or `n` where `n` will be used
   * in both the `x` and `y` axis.
   *
   * For example, to move a menu by `2px` from the top, we can use:
   * <hljs lang="html">
   * <md-menu md-offset="2 0">
   *   <!-- menu-content -->
   * </md-menu>
   * </hljs>
   *
   * @usage
   * <hljs lang="html">
   * <md-menu>
   *  <md-button ng-click="$mdOpenMenu($event)" class="md-icon-button">
   *    <md-icon md-svg-icon="call:phone"></md-icon>
   *  </md-button>
   *  <md-menu-content>
   *    <md-menu-item><md-button ng-click="doSomething()">Do Something</md-button></md-menu-item>
   *  </md-menu-content>
   * </md-menu>
   * </hljs>
   *
   * @param {string} md-po*ition-mode The position mode in the form of
   *           `x`, `y`. Default value is `target`,`target`. Right now the `x` axis
   *           also suppports `target-right`.
   * @param {string} md-offset An offset to apply to the dropdown after positioning
   *           `x`, `y`. Default value is `0`,`0`.

   * Use the `<md-tab>` a nested directive used within `<md-tabs>` to specify a tab with a **label** and optional *view content*.
   *
   * If the `label` attribute is not specified, then an optional `<md-tab-label>` tag can be used to specify more
   * complex tab header markup. If neither the **label** nor the **md-tab-label** are specified, then the nested
   * markup of the `<md-tab>` is used as the tab header markup.
   *
   * Please note that if you use `<md-tab-label>`, your content **MUST** be wrapped in the `<md-tab-body>` tag.  This
   * is to define a clear separation between the tab content and the tab label.
   *
   * If a tab **label** has been identified, then any **non-**`<md-tab-label>` markup
   * will be considered tab content and will be transcluded to the internal `<div class="md-tabs-content">` container.
   *
   * This container is used by the TabsController to show/hide the active tab's content view. This synchronization is
   * automatically managed by the internal TabsController whenever the tab selection changes. Selection changes can
   * be initiated via data binding changes, programmatic invocation, or user gestures.
   *
   * @param {string=} label Optional attribute to specify a simple string as the tab label
   * @param {boolean=} disabled If present, disabled tab selection.
   * @param {expression=} md-on-deselect Expression to be evaluated after the tab has been de-selected.
   * @param {expression=} md-on-select Expression to be evaluated after the tab has been selected.

   *
   * @description
   * The `<md-tabs>` directive serves as the container for 1..n `<md-tab>` child directives to produces a Tabs components.
   * In turn, the nested `<md-tab>` directive is used to specify a tab label for the **header button** and a [optional] tab view
   * content that will be associated with each tab button.
   *
   * Below is the markup for its simplest usage:
   *
   *  <hljs lang="html">
   *  <md-tabs>
   *    <md-tab label="Tab #1"></md-tab>
   *    <md-tab label="Tab #2"></md-tab>
   *    <md-tab label="Tab #3"></md-tab>
   *  </md-tabs>
   *  </hljs>
   *
   * Tabs supports three (3) usage scenarios:
   *
   *  1. Tabs (buttons only)
   *  2. Tabs with internal view content
   *  3. Tabs with external view content
   *
   * **Tab-only** support is useful when tab buttons are used for custom navigation regardless of any other components, content, or views.
   * **Tabs with internal views** are the traditional usages where each tab has associated view content and the view switching is managed internally by the Tabs component.
   * **Tabs with external view content** is often useful when content associated with each tab is independently managed and data-binding notifications announce tab selection changes.
   *
   * Additional features also include:
   *
   * *  Content can include any markup.
   * *  If a tab is disabled while active/selected, then the next tab will be auto-selected.
   *
   * ### Explanation of tab stretching
   *
   * Initially, tabs will have an inherent size.  This size will either be defined by how much space is needed to accommodate their text or set by the user through CSS.  Calculations will be based on this size.
   *
   * On mobile devices, tabs will be expanded to fill the available horizontal space.  When this happens, all tabs will become the same size.
   *
   * On desktops, by default, stretching will never occur.
   *
   * This default behavior can be overridden through the `md-stretch-tabs` attribute.  Here is a table showing when stretching will occur:
   *
   * `md-stretch-tabs` | mobile    | desktop
   * ------------------|-----------|--------
   * `auto`            | stretched | ---
   * `always`          | stretched | stretched
   * `never`           | ---       | ---
   *
   * @param {integer=} md-selected Index of the active/selected tab
   * @param {boolean=} md-no-ink If present, disables ink ripple effects.
   * @param {boolean=} md-no-bar If present, disables the selection ink bar.
   * @param {string=}  md-align-tabs Attribute to indicate position of tab buttons: `bottom` or `top`; default is `top`
   * @param {string=} md-stretch-tabs Attribute to indicate whether or not to stretch tabs: `auto`, `always`, or `never`; default is `auto`
   * @param {boolean=} md-dynamic-height When enabled, the tab wrapper will resize based on the contents of the selected tab
   * @param {boolean=} md-center-tabs When enabled, tabs will be centered provided there is no need for pagination
   * @param {boolean=} md-no-pagination When enabled, pagination will remain off
   * @param {boolean=} md-swipe-content When enabled, swipe gestures will be enabled for the content area to jump between tabs
   * @param {boolean=} md-no-disconnect If your tab content has background tasks (ie. event listeners), you will want to include this to prevent the scope from being disconnected
   * @param {boolean=} md-autoselect When present, any tabs added after the initial load will be automatically selected
   *
   * @usage
   * <hljs lang="html">
   * <md-tabs md-selected="selectedIndex" >
   *   <img ng-src="img/angular.png" class="centered">
   *   <md-tab
