    *      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.
    *

    *
    *   - `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. These values will not be available until after initialization.

/* 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-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

 *   - `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.

 *
 * @description
 * The checkbox directive is used like the normal [angular checkbox](https://docs.angularjs.org/api/ng/input/input%5Bcheckbox%5D).
 *
 * As per the [material design spec](http://www.google.com/design/spec/style/color.html#color-ui-color-application)
 * the checkbox is in the accent color by default. The primary color palette may be used with
 * the `md-primary` class.
 *
 * @param {string} ng-model Assignable angular expression to data-bind to.
 * @param {string=} name Property name of the form under which the control is published.
 * @param {expression=} ng-true-value The value to which the expression should be set when selected.
 * @param {expression=} ng-false-value The value to which the expression should be set when not selected.
 * @param {string=} ng-change Angular expression to be executed when input changes due to user interaction with the input element.
 * @param {boolean=} md-no-ink Use of attribute indicates use of ripple ink effects
 * @param {string=} aria-label Adds label to checkbox for accessibility.
 * Defaults to checkbox's text. If no default text is found, a warning will be logged.
 *
 * @usage
 * <hljs lang="html">

/**
 * @ngdoc service
 * @name $mdDialog
 * @module material.components.dialog
 *
 * @description
 * `$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`.

 * @description
 * Show a dialog with the specified options.
 *
 * @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.
 *
 * @returns {promise} A promise that can be resolved with `$mdDialog.hide()` or
 * rejected with `$mdDialog.cancel()`.

 * @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"

 * following convention: `{base-attribute-name}-{media-query-name}="{value}"`
 * (ie. `md-colspan-sm="4"`)
 *
 * @param {number=} md-colspan The number of columns to span (default 1). Cannot
 *    exceed the number of columns in the grid. Supports interpolation.

 * The `<md-radio-group>` directive identifies a grouping
 * container for the 1..n grouped radio buttons; specified using nested
 * `<md-radio-button>` tags.
 *
 * As per the [material design spec](http://www.google.com/design/spec/style/color.html#color-ui-color-application)
 * the radio button is in the accent color by default. The primary color palette may be used with
 * the `md-primary` class.
 *
 * Note: `<md-radio-group>` and `<md-radio-button>` handle tabindex differently
 * than the native `<input type='radio'>` controls. Whereas the native controls
 * force the user to tab through all the radio buttons, `<md-radio-group>`
 * is focusable, and by default the `<md-radio-button>`s are not.
 *
 * @param {string} ng-model Assignable angular expression to data-bind to.
 * @param {boolean=} md-no-ink Use of attribute indicates flag to disable ink ripple effects.

 *   - `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 `$hideToast`, 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.

 * @ngdoc directive
 * @name mdTooltip
 * @module material.components.tooltip
 * @description
 * Tooltips are used to describe elements that are interactive and primarily graphical (not textual).
 *
 * Place a `<md-tooltip>` as a child of the element it describes.
 *
 * A tooltip will activate when the user focuses, hovers over, or touches the parent.
 *
 * @usage
 * <hljs lang="html">
 * <md-button class="md-fab md-accent" aria-label="Play">
 *   <md-tooltip>
 *     Play Music
 *   </md-tooltip>
 *   <md-icon icon="/img/icons/ic_play_arrow_24px.svg"></md-icon>
 * </md-button>
 * </hljs>
 *
 * @param {expression=} md-visible Boolean bound to whether the tooltip is
 * currently visible.
 * @param {number=} md-delay How many milliseconds to wait to show the tooltip after the user focuses, hovers, or touches the parent. Defaults to 400ms.
 * @param {string=} md-direction Which direction would you like the tooltip to go?  Supports left, right, top, and bottom.  Defaults to bottom.
 * @param {boolean=} md-autohide If present or provided with a boolean value, the tooltip will hide on mouse leave, regardless of focus

/**
 * @ngdoc directive
 * @name mdChips
 * @module material.components.chips
 *
 * @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.
 *
 * <h3> Pending Features </h3>

/**
 * @ngdoc directive
 * @name mdTabs
 * @module material.components.tabs
 *
 * @restrict E
 *
 * @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
 *
 * @usage
 * <hljs lang="html">
 * <md-tabs md-selected="selectedIndex" >
 *   <img ng-src="img/angular.png" class="centered">
 *   <md-tab
 *       ng-repeat="tab in tabs | orderBy:predicate:reversed"
 *       md-on-select="onTabSelected(tab)"
 *       md-on-deselect="announceDeselected(tab)"
 *       ng-disabled="tab.disabled">
