 * @ngdoc service
 * @name $ionicActionSheet
 * @module ionic
 * @description
 * The Action Sheet is a slide-up pane that lets the user choose from a set of options.
 * Dangerous options are highlighted in red and made obvious.
 *
 * There are easy ways to cancel out of the action sheet, such as tapping the backdrop or even
 * hitting escape on the keyboard for desktop testing.
 *
 * ![Action Sheet](http://ionicframework.com.s3.amazonaws.com/docs/controllers/actionSheet.gif)
 *
 * @usage
 * To trigger an Action Sheet in your code, use the $ionicActionSheet service in your angular controllers:
 *
 * ```js
 * angular.module('mySuperApp', ['ionic'])
 * .controller(function($scope, $ionicActionSheet) {
 *
 *  // Triggered on a button click, or some other target
 *  $scope.show = function() {
 *
 *    // Show the action sheet
 *    $ionicActionSheet.show({
 *      buttons: [
 *        { text: 'Share' },
 *        { text: 'Move' },
 *      ],
 *      destructiveText: 'Delete',
 *      titleText: 'Modify your album',
 *      cancelText: 'Cancel',
 *      buttonClicked: function(index) {
 *        return true;

/**
 * @ngdoc service
 * @name $ionicBackdrop
 * @module ionic
 * @description
 * Shows and hides a backdrop over the UI.  Appears behind popups, loading,
 * and other overlays.
 *
 * Often, multiple UI components require a backdrop, but only one backdrop is
 * ever needed in the DOM at a time.
 *
 * Therefore, each component that requires the backdrop to be shown calls
 * `$ionicBackdrop.retain()` when it wants the backdrop, then `$ionicBackdrop.release()`
 * when it is done with the backdrop.
 *
 * For each time `retain` is called, the backdrop will be shown until `release` is called.
 *
 * For example, if `retain` is called three times, the backdrop will be shown until `release`
 * is called three times.
 *
 * @usage
 *
 * ```js
 * function MyController($scope, $ionicBackdrop, $timeout) {
 *   //Show a backdrop for one second
 *   $scope.action = function() {
 *     $ionicBackdrop.retain();

/**
 * @ngdoc directive
 * @module ionic
 * @name collectionRepeat
 * @restrict A
 * @codepen mFygh
 * @description
 * `collection-repeat` is a directive that allows you to render lists with
 * thousands of items in them, and experience little to no performance penalty.
 *
 * Demo:
 *
 * The directive renders onto the screen only the items that should be currently visible.
 * So if you have 1,000 items in your list but only ten fit on your screen,
 * collection-repeat will only render into the DOM the ten that are in the current
 * scroll position.
 *
 * Here are a few things to keep in mind while using collection-repeat:
 *
 * 1. The data supplied to collection-repeat must be an array.
 * 2. You must explicitly tell the directive what size your items will be in the DOM
 * (pixel amount or percentage), using directive attributes (see below).
 * 3. The elements rendered will be absolutely positioned: be sure to let your CSS work with this (see below).
 * 4. Keep the HTML of your repeated elements as simple as possible. As the user scrolls down, elements
 * will be lazily compiled. Resultingly, the more complicated your elements, the more likely it is that
 * the on-demand compilation will cause jankiness in the user's scrolling.
 * 5. The more elements you render on the screen at a time, the slower the scrolling will be.
 * It is recommended to keep grids of collection-repeat list elements at 3-wide or less.
 * 6. Each collection-repeat list will take up all of its parent scrollView's space.
 * If you wish to have multiple lists on one page, put each list within its own
 * {@link ionic.directive:ionScroll ionScroll} container.
 *
 *
 *
 * @usage
 *
 * #### Basic Usage (single rows of items)
 *
 * Notice two things here: we use ng-style to set the height of the item to match
 * what the repeater thinks our item height is.  Additionally, we add a css rule
 * to make our item stretch to fit the full screen (since it will be absolutely
 * positioned).
 *
 * ```html
 * <ion-content ng-controller="ContentCtrl">
 *   <div class="list">
 *     <div class="item my-item"
 *       collection-repeat="item in items"
 *       collection-item-width="100%"
 *       collection-item-height="getItemHeight(item, $index)"
 *       ng-style="{height: getItemHeight(item, $index)}">
 *       {% raw %}{{item}}{% endraw %}
 *     </div>
 *   </div>
 * </div>
 * ```
 * ```js
 * function ContentCtrl($scope) {
 *   $scope.items = [];
 *   for (var i = 0; i < 1000; i++) {
 *     $scope.items.push('Item ' + i);
 *   }
 *
 *   $scope.getItemHeight = function(item, index) {
 *     //Make evenly indexed items be 10px taller, for the sake of example
 *     return (index % 2) === 0 ? 50 : 60;
 *   };
 * }
 * ```
 * ```css
 * .my-item {
 *   left: 0;
 *   right: 0;
 * }
 * ```
 *
 * #### Grid Usage (three items per row)
 *
 * ```html
 * <ion-content>
 *   <div class="item item-avatar my-image-item"
 *     collection-repeat="image in images"
 *     collection-item-width="33%"
 *     collection-item-height="33%">
 *     <img ng-src="{{image.src}}">
 *   </div>
 * </ion-content>
 * ```
 * ```css
 * .my-image-item {
 *   height: 33%;
 *   width: 33%;
 * }
 * ```
 *
 * @param {expression} collection-repeat The expression indicating how to enumerate a collection. These
 *   formats are currently supported:
 *
 *   * `variable in expression` – where variable is the user defined loop variable and `expression`
 *     is a scope expression giving the collection to enumerate.
 *
 *     For example: `album in artist.albums`.
 *
 *   * `variable in expression track by tracking_expression` – You can also provide an optional tracking function
 *     which can be used to associate the objects in the collection with the DOM elements. If no tracking function
 *     is specified the collection-repeat associates elements by identity in the collection. It is an error to have
 *     more than one tracking function to resolve to the same key. (This would mean that two distinct objects are
 *     mapped to the same DOM element, which is not possible.)  Filters should be applied to the expression,
 *     before specifying a tracking expression.
 *
 *     For example: `item in items` is equivalent to `item in items track by $id(item)'. This implies that the DOM elements
 *     will be associated by item identity in the array.
 *
 *     For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique
 *     `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements
 *     with the corresponding item in the array by identity. Moving the same object in array would move the DOM
 *     element in the same way in the DOM.
 *
 *     For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this
 *     case the object identity does not matter. Two objects are considered equivalent as long as their `id`
 *     property is same.
 *
 *     For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter
 *     to items in conjunction with a tracking expression.
 *
 * @param {expression} collection-item-width The width of the repeated element.  Can be a number (in pixels) or a percentage.
 * @param {expression} collection-item-height The height of the repeated element.  Can be a number (in pixels), or a percentage.

* @description
* The List is a widely used interface element in almost any mobile app, and can include
* content ranging from basic text all the way to buttons, toggles, icons, and thumbnails.
*
* Both the list, which contains items, and the list items themselves can be any HTML
* element. The containing element requires the `list` class and each list item requires
* the `item` class.
*
* However, using the ionList and ionItem directives make it easy to support various
* interaction modes such as swipe to edit, drag to reorder, and removing items.
*
* Related: {@link ionic.directive:ionItem}, {@link ionic.directive:ionOptionButton}
* {@link ionic.directive:ionReorderButton}, {@link ionic.directive:ionDeleteButton}, [`list CSS documentation`](/docs/components/#list).

/**
 * @ngdoc directive
 * @name ionNavView
 * @module ionic
 * @restrict E
 * @codepen HjnFx
 *
 * @description
 * As a user navigates throughout your app, Ionic is able to keep track of their
 * navigation history. By knowing their history, transitions between views
 * correctly slide either left or right, or no transition at all. An additional
 * benefit to Ionic's navigation system is its ability to manage multiple
 * histories.
 *
 * Ionic uses the AngularUI Router module so app interfaces can be organized
 * into various "states". Like Angular's core $route service, URLs can be used
 * to control the views. However, the AngularUI Router provides a more powerful
 * state manager in that states are bound to named, nested, and parallel views,
 * allowing more than one template to be rendered on the same page.
 * Additionally, each state is not required to be bound to a URL, and data can
 * be pushed to each state which allows much flexibility.
 *
 * The ionNavView directive is used to render templates in your application. Each template
 * is part of a state. States are usually mapped to a url, and are defined programatically
 * using angular-ui-router (see [their docs](https://github.com/angular-ui/ui-router/wiki),
 * and remember to replace ui-view with ion-nav-view in examples).
 *
 * @usage
 * In this example, we will create a navigation view that contains our different states for the app.
 *
 * To do this, in our markup we use ionNavView top level directive. To display a header bar we use
 * the {@link ionic.directive:ionNavBar} directive that updates as we navigate through the
 * navigation stack.
 *
 * You can any [animation class](/docs/components#animation) on the navView to have its pages slide.
 * Recommended for page transitions: 'slide-left-right', 'slide-left-right-ios7', 'slide-in-up'.
 *
 * ```html
 * <ion-nav-bar></ion-nav-bar>
 * <ion-nav-view class="slide-left-right">
 *   <!-- Center content -->
 * </ion-nav-view>
 * ```
 *
 * Next, we need to setup our states that will be rendered.
 *
 * ```js
 * var app = angular.module('myApp', ['ionic']);
 * app.config(function($stateProvider) {
 *   $stateProvider
 *   .state('index', {
 *     url: '/',
 *     templateUrl: 'home.html'
 *   })
 *   .state('music', {
 *     url: '/music',
 *     templateUrl: 'music.html'
 *   });
 * });
 * ```
 * Then on app start, $stateProvider will look at the url, see it matches the index state,
 * and then try to load home.html into the `<ion-nav-view>`.
 *
 * Pages are loaded by the URLs given. One simple way to create templates in Angular is to put
 * them directly into your HTML file and use the `<script type="text/ng-template">` syntax.
 * So here is one way to put home.html into our app:
 *
 * ```html
 * <script id="home" type="text/ng-template">
 *   <!-- The title of the ion-view will be shown on the navbar -->
 *   <ion-view title="'Home'">
 *     <ion-content ng-controller="HomeCtrl">
 *       <!-- The content of the page -->
 *       <a href="#/music">Go to music page!</a>
 *     </ion-content>
 *   </ion-view>
 * </script>
 * ```
 *
 * This is good to do because the template will be cached for very fast loading, instead of
 * having to fetch them from the network.
 *
 * Please visit [AngularUI Router's docs](https://github.com/angular-ui/ui-router/wiki) for
 * more info. Below is a great video by the AngularUI Router guys that may help to explain
 * how it all works:
 *
 * <iframe width="560" height="315" src="//www.youtube.com/embed/dqJRoh8MnBo"
 * frameborder="0" allowfullscreen></iframe>
 *
 * @param {string=} name A view name. The name should be unique amongst the other views in the
 * same state. You can have views of the same name that live in different states. For more
 * information, see ui-router's [ui-view documentation](http://angular-ui.github.io/ui-router/site/#/api/ui.router.state.directive:ui-view).
