/**
 * @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, $timeout) {
 *
 *  // Triggered on a button click, or some other target
 *  $scope.show = function() {
 *
 *    // Show the action sheet
 *    var hideSheet = $ionicActionSheet.show({
 *      buttons: [
 *        { text: '<b>Share</b> This' },
 *        { text: 'Move' }
 *      ],
 *      destructiveText: 'Delete',
 *      titleText: 'Modify your album',
 *      cancelText: 'Cancel',
 *      cancel: function() {
          // add cancel code..
        },
 *      buttonClicked: function(index) {
 *        return true;
 *      }
 *    });
 *
 *    // For example's sake, hide the sheet after two seconds
 *    $timeout(function() {
 *      hideSheet();
 *    }, 2000);
 *
 *  };
 * });
 * ```

/**
 * @ngdoc service

 * Shows and hides a backdrop over the UI.  Appears behind popups, loading,

 *
 * 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
 *

/**
 * @ngdoc provider
 * @name $ionicConfigProvider
 * @module ionic
 * @description
 * Ionic automatically takes platform configurations into account to adjust things like what
 * transition style to use and whether tab icons should show on the top or bottom. For example,
 * iOS will move forward by transitioning the entering view from right to center and the leaving
 * view from center to left. However, Android will transition with the entering view going from
 * bottom to center, covering the previous view, which remains stationary. It should be noted
 * that when a platform is not iOS or Android, then it'll default to iOS. So if you are
 * developing on a desktop browser, it's going to take on iOS default configs.
 *
 * These configs can be changed using the `$ionicConfigProvider` during the configuration phase
 * of your app. Additionally, `$ionicConfig` can also set and get config values during the run
 * phase and within the app itself.
 *
 * By default, all base config variables are set to `'platform'`, which means it'll take on the
 * default config of the platform on which it's running. Config variables can be set at this
 * level so all platforms follow the same setting, rather than its platform config.
 * The following code would set the same config variable for all platforms:
 *
 * ```js
 * $ionicConfigProvider.views.maxCache(10);
 * ```
 *
 * Additionally, each platform can have it's own config within the `$ionicConfigProvider.platform`
 * property. The config below would only apply to Android devices.
 *
 * ```js
 * $ionicConfigProvider.platform.android.views.maxCache(5);
 * ```
 *
 * @usage
 * ```js
 * var myApp = angular.module('reallyCoolApp', ['ionic']);
 *
 * myApp.config(function($ionicConfigProvider) {
 *   $ionicConfigProvider.views.maxCache(5);
 *
 *   // note that you can also chain configs
 *   $ionicConfigProvider.backButton.text('Go Back').icon('ion-chevron-left');
 * });
 * ```

/**
 * @ngdoc service
 * @name $ionicModal
 * @module ionic
 * @description
 *
 * Related: {@link ionic.controller:ionicModal ionicModal controller}.
 *
 * The Modal is a content pane that can go over the user's main view
 * temporarily.  Usually used for making a choice or editing an item.
 *
 * Put the content of the modal inside of an `<ion-modal-view>` element.
 *
 * **Notes:**
 * - A modal will broadcast 'modal.shown', 'modal.hidden', and 'modal.removed' events from its originating
 * scope, passing in itself as an event argument. Both the modal.removed and modal.hidden events are
 * called when the modal is removed.
 *
 * - This example assumes your modal is in your main index file or another template file. If it is in its own
 * template file, remove the script tags and call it by file name.
 *
 * @usage
 * ```html
 * <script id="my-modal.html" type="text/ng-template">
 *   <ion-modal-view>
 *     <ion-header-bar>
 *       <h1 class="title">My Modal title</h1>
 *     </ion-header-bar>
 *     <ion-content>
 *       Hello!
 *     </ion-content>
 *   </ion-modal-view>
 * </script>
 * ```
 * ```js
 * angular.module('testApp', ['ionic'])
 * .controller('MyController', function($scope, $ionicModal) {
 *   $ionicModal.fromTemplateUrl('my-modal.html', {
 *     scope: $scope,

 *
 * The Ionic Popup service allows programmatically creating and showing popup
 * windows that require the user to respond in order to continue.
 *
 * The popup system has support for more flexible versions of the built in `alert()`, `prompt()`,
 * and `confirm()` functions that users are used to, in addition to allowing popups with completely
 * custom content and look.
 *
 * An input can be given an `autofocus` attribute so it automatically receives focus when
 * the popup first shows. However, depending on certain use-cases this can cause issues with
 * the tap/click system, which is why Ionic prefers using the `autofocus` attribute as
 * an opt-in feature and not the default.
 *
 * @usage
 * A few basic examples, see below for details about all of the options available.
 *
 * ```js
 *angular.module('mySuperApp', ['ionic'])

 *
 * // Triggered on a button click, or some other target
 * $scope.showPopup = function() {
 *   $scope.data = {}
 *
 *   // An elaborate, custom popup
 *   var myPopup = $ionicPopup.show({
 *     template: '<input type="password" ng-model="data.wifi">',
 *     title: 'Enter Wi-Fi Password',
 *     subTitle: 'Please use normal things',
 *     scope: $scope,
 *     buttons: [
 *       { text: 'Cancel' },
 *       {
 *         text: '<b>Save</b>',
 *         type: 'button-positive',
 *         onTap: function(e) {
 *           if (!$scope.data.wifi) {
 *             //don't allow the user to close unless he enters wifi password
 *             e.preventDefault();

/**
 * @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, using directive attributes.
 * Pixel amounts or percentages are allowed (see below).
 * 3. The elements rendered will be absolutely positioned: be sure to let your CSS work with
 * this (see below).
 * 4. 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.
 * 5. You should not use the ng-show and ng-hide directives on your ion-content/ion-scroll elements that
 * have a collection-repeat inside.  ng-show and ng-hide apply the `display: none` css rule to the content's
 * style, causing the scrollView to read the width and height of the content as 0.  Resultingly,
 * collection-repeat will render elements that have just been un-hidden incorrectly.
 *
 *
 * @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, $index)}">
 *       {% raw %}{{item}}{% endraw %}
 *     </div>
 *   </div>
 * </ion-content>
 * ```
 * ```js
 * function ContentCtrl($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>
 * ```
 * Percentage of total visible list dimensions. This example shows a 3 by 3 matrix that fits on the screen (3 rows and 3 colums). Note that dimensions are used in the creation of the element and therefore a measurement of the item cannnot be used as an input dimension.
 * ```css
 * .my-image-item img {
 *   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.
 *

 * The ionContent directive provides an easy to use content area that can be configured
 * to use Ionic's custom Scroll View, or the built in overflow scrolling of the browser.
 *
 * While we recommend using the custom Scroll features in Ionic in most cases, sometimes
 * (for performance reasons) only the browser's native overflow scrolling will suffice,
 * and so we've made it easy to toggle between the Ionic scroll implementation and
 * overflow scrolling.
 *
 * You can implement pull-to-refresh with the {@link ionic.directive:ionRefresher}
 * directive, and infinite scrolling with the {@link ionic.directive:ionInfiniteScroll}
 * directive.
 *
 * Be aware that this directive gets its own child scope. If you do not understand why this
 * is important, you can read [https://docs.angularjs.org/guide/scope](https://docs.angularjs.org/guide/scope).
 *
 * @param {string=} delegate-handle The handle used to identify this scrollView
 * with {@link ionic.service:$ionicScrollDelegate}.
 * @param {string=} direction Which way to scroll. 'x' or 'y' or 'xy'. Default 'y'.
 * @param {boolean=} locking Whether to lock scrolling in one direction at a time. Useful to set to false when zoomed in or scrolling in two directions. Default true.
 * @param {boolean=} padding Whether to add padding to the content.
 * of the content.  Defaults to true on iOS, false on Android.
 * @param {boolean=} scroll Whether to allow scrolling of content.  Defaults to true.
 * @param {boolean=} overflow-scroll Whether to use overflow-scrolling instead of
 * Ionic scroll.
 * @param {boolean=} scrollbar-x Whether to show the horizontal scrollbar. Default true.
 * @param {boolean=} scrollbar-y Whether to show the vertical scrollbar. Default true.
 * @param {string=} start-x Initial horizontal scroll position. Default 0.
 * @param {string=} start-y Initial vertical scroll position. Default 0.
 * @param {expression=} on-scroll Expression to evaluate when the content is scrolled.
 * @param {expression=} on-scroll-complete Expression to evaluate when a scroll action completes.
 * @param {boolean=} has-bouncing Whether to allow scrolling to bounce past the edges
 * of the content.  Defaults to true on iOS, false on Android.
 * @param {number=} scroll-event-interval Number of milliseconds between each firing of the 'on-scroll' expression. Default 10.

/**
 * @ngdoc directive
 * @name exposeAsideWhen
 * @module ionic
 * @restrict A
 * @parent ionic.directive:ionSideMenus
 *
 * @description
 * It is common for a tablet application to hide a menu when in portrait mode, but to show the
 * same menu on the left side when the tablet is in landscape mode. The `exposeAsideWhen` attribute
 * directive can be used to accomplish a similar interface.
 *
 * By default, side menus are hidden underneath its side menu content, and can be opened by either
 * swiping the content left or right, or toggling a button to show the side menu. However, by adding the
 * `exposeAsideWhen` attribute directive to an {@link ionic.directive:ionSideMenu} element directive,
 * a side menu can be given instructions on "when" the menu should be exposed (always viewable). For
 * example, the `expose-aside-when="large"` attribute will keep the side menu hidden when the viewport's
 * width is less than `768px`, but when the viewport's width is `768px` or greater, the menu will then
 * always be shown and can no longer be opened or closed like it could when it was hidden for smaller
 * viewports.
 *
 * Using `large` as the attribute's value is a shortcut value to `(min-width:768px)` since it is
 * the most common use-case. However, for added flexibility, any valid media query could be added
 * as the value, such as `(min-width:600px)` or even multiple queries such as
 * `(min-width:750px) and (max-width:1200px)`.

 * @usage
 * ```html
 * <ion-side-menus>
 *   <!-- Center content -->
 *   <ion-side-menu-content>
 *   </ion-side-menu-content>
 *
 *   <!-- Left menu -->
 *   <ion-side-menu expose-aside-when="large">
 *   </ion-side-menu>
 * </ion-side-menus>
 * ```
 * For a complete side menu example, see the
 * {@link ionic.directive:ionSideMenus} documentation.

 * @restrict E
 *
 * @description
 * The ionInfiniteScroll directive allows you to call a function whenever
 * the user gets to the bottom of the page or near the bottom of the page.
 *
 * The expression you pass in for `on-infinite` is called when the user scrolls
 * greater than `distance` away from the bottom of the content.  Once `on-infinite`
 * is done loading new data, it should broadcast the `scroll.infiniteScrollComplete`
 * event from your controller (see below example).
 *
 * @param {expression} on-infinite What to call when the scroller reaches the
 * bottom.
 * @param {string=} distance The distance from the bottom that the scroll must
 * reach to trigger the on-infinite expression. Default: 1%.
 * @param {string=} icon The icon to show while loading. Default: 'ion-loading-d'.
 *
 * @usage
 * ```html
 * <ion-content ng-controller="MyController">
 *   <ion-list>
 *   ....
 *   ....
 *   </ion-list>
 *
 *   <ion-infinite-scroll
 *     on-infinite="loadMore()"
 *     distance="1%">
 *   </ion-infinite-scroll>
 * </ion-content>
 * ```
 * ```js
 * function MyController($scope, $http) {
 *   $scope.items = [];
 *   $scope.loadMore = function() {
 *     $http.get('/more-items').success(function(items) {
 *       useItems(items);

 *     });
 *   };
 *
 *   $scope.$on('$stateChangeSuccess', function() {
 *     $scope.loadMore();
 *   });
 * }
 * ```
 *
 * An easy to way to stop infinite scroll once there is no more data to load
 * is to use angular's `ng-if` directive:
 *
 * ```html
 * <ion-infinite-scroll
 *   ng-if="moreDataCanBeLoaded()"
 *   icon="ion-loading-c"
 *   on-infinite="loadMoreData()">
 * </ion-infinite-scroll>

 * possible, as outlined below.
 *
 * @usage

 * Recommended markup for default settings:
 *
 * ```html
 * <ion-nav-bar>
 *   <ion-nav-back-button>
 *   </ion-nav-back-button>
 * </ion-nav-bar>
 * ```
 *

 *
 * @description
 * If we have an {@link ionic.directive:ionNavView} directive, we can also create an
 * `<ion-nav-bar>`, which will create a topbar that updates as the application state changes.
 *
 * We can add a back button by putting an {@link ionic.directive:ionNavBackButton} inside.
 *
 * We can add buttons depending on the currently visible view using
 * {@link ionic.directive:ionNavButtons}.
 *
 * Note that the ion-nav-bar element will only work correctly if your content has an
 * ionView around it.
 *
 * @usage
 *
 * ```html
 * <body ng-app="starter">
 *   <!-- The nav bar that will be updated as we navigate -->
 *   <ion-nav-bar class="bar-positive">
 *   </ion-nav-bar>
 *

 * </body>
 * ```
 *
 * @param {string=} delegate-handle The handle used to identify this navBar
 * with {@link ionic.service:$ionicNavBarDelegate}.
 * @param align-title {string=} Where to align the title of the navbar.
 * Available: 'left', 'right', 'center'. Defaults to 'center'.
 * @param {boolean=} no-tap-scroll By default, the navbar will scroll the content
 * to the top when tapped.  Set no-tap-scroll to true to disable this behavior.
 *
 * </table><br/>
 *
 * ### Alternative Usage
 *
 * Alternatively, you may put ion-nav-bar inside of each individual view's ion-view element.
 * This will allow you to have the whole navbar, not just its contents, transition every view change.
 *
 * This is similar to using a header bar inside your ion-view, except it will have all the power of a navbar.
 *
 * If you do this, simply put nav buttons inside the navbar itself; do not use `<ion-nav-buttons>`.
 *
 *

 * from within an {@link ionic.directive:ionView}. This gives each
 * view template the ability to specify which buttons should show in the nav bar,
 * overriding any default buttons already placed in the nav bar.
 *
 * Any buttons you declare will be positioned on the navbar's corresponding side. Primary
 * buttons generally map to the left side of the header, and secondary buttons are
 * generally on the right side. However, their exact locations are platform-specific.
 * For example, in iOS, the primary buttons are on the far left of the header, and
 * secondary buttons are on the far right, with the header title centered between them.
 * For Android, however, both groups of buttons are on the far right of the header,
 * with the header title aligned left.
 *
 * We recommend always using `primary` and `secondary`, so the buttons correctly map
 * to the side familiar to users of each platform. However, in cases where buttons should
 * always be on an exact side, both `left` and `right` sides are still available. For
 * example, a toggle button for a left side menu should be on the left side; in this case,
 * we'd recommend using `side="left"`, so it's always on the left, no matter the platform.
 *
 * Note that `ion-nav-buttons` must be immediate descendants of the `ion-view` or

/**
 * @ngdoc directive
 * @name ionNavView
 * @module ionic
 * @restrict E
 * @codepen odqCz
 *
 * @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 enter and exit using the platform's transition style. An additional
 * benefit to Ionic's navigation system is its ability to manage multiple
 * histories. For example, each tab can have it's own navigation history stack.
 *
 * Ionic uses the AngularUI Router module so app interfaces can be organized
 * into various "states". Like Angular's core $route service, URLs can be used
 * to control the views. However, the AngularUI Router provides a more powerful
 * state manager in that states are bound to named, nested, and parallel views,
 * allowing more than one template to be rendered on the same page.
 * Additionally, each state is not required to be bound to a URL, and data can
 * be pushed to each state which allows much flexibility.
 *
 * The ionNavView directive is used to render templates in your application. Each template
 * is part of a state. States are usually mapped to a url, and are defined programatically
 * using angular-ui-router (see [their docs](https://github.com/angular-ui/ui-router/wiki),
 * and remember to replace ui-view with ion-nav-view in examples).
 *
 * @usage
 * In this example, we will create a navigation view that contains our different states for the app.
 *
 * To do this, in our markup we use ionNavView top level directive. To display a header bar we use
 * the {@link ionic.directive:ionNavBar} directive that updates as we navigate through the
 * navigation stack.
 *
 * Next, we need to setup our states that will be rendered.
 *
 * ```js
 * var app = angular.module('myApp', ['ionic']);
 * app.config(function($stateProvider) {
 *   $stateProvider
 *   .state('index', {
 *     url: '/',
 *     templateUrl: 'home.html'
 *   })
 *   .state('music', {
 *     url: '/music',
 *     templateUrl: 'music.html'
 *   });
 * });
 * ```
 * Then on app start, $stateProvider will look at the url, see it matches the index state,
 * and then try to load home.html into the `<ion-nav-view>`.
 *
 * Pages are loaded by the URLs given. One simple way to create templates in Angular is to put
 * them directly into your HTML file and use the `<script type="text/ng-template">` syntax.
 * So here is one way to put home.html into our app:
 *
 * ```html
 * <script id="home" type="text/ng-template">
 *   <!-- The title of the ion-view will be shown on the navbar -->
 *   <ion-view view-title="Home">
 *     <ion-content ng-controller="HomeCtrl">
 *       <!-- The content of the page -->
 *       <a href="#/music">Go to music page!</a>
 *     </ion-content>
 *   </ion-view>
 * </script>
 * ```
 *
 * This is good to do because the template will be cached for very fast loading, instead of
 * having to fetch them from the network.
 *
 ## Caching
 *
 * By default, views are cached to improve performance. When a view is navigated away from, its
 * element is left in the DOM, and its scope is disconnected from the `$watch` cycle. When
 * navigating to a view that is already cached, its scope is then reconnected, and the existing
 * element that was left in the DOM becomes the active view. This also allows for the scroll
 * position of previous views to be maintained.
 *
 * Caching can be disabled and enabled in multiple ways. By default, Ionic will cache a maximum of
 * 10 views, and not only can this be configured, but apps can also explicitly state which views
 * should and should not be cached.
 *
 * Note that because we are caching these views, *we aren’t destroying scopes*. Instead, scopes
 * are being disconnected from the watch cycle. Because scopes are not being destroyed and
 * recreated, controllers are not loading again on a subsequent viewing. If the app/controller
 * needs to know when a view has entered or has left, then view events emitted from the
 * {@link ionic.directive:ionView} scope, such as `$ionicView.enter`, may be useful
 *
 * #### Disable cache globally
 *
 * The {@link ionic.provider:$ionicConfigProvider} can be used to set the maximum allowable views
 * which can be cached, but this can also be use to disable all caching by setting it to 0.
 *
 * ```js
 * $ionicConfigProvider.views.maxCache(0);
 * ```
 *
 * #### Disable cache within state provider
 *
 * ```js
 * $stateProvider.state('myState', {
 *    cache: false,
 *    url : '/myUrl',
 *    templateUrl : 'my-template.html'
 * })
 * ```
 *
 * #### Disable cache with an attribute
 *
 * ```html
 * <ion-view cache-view="false" view-title="My Title!">
 *   ...
 * </ion-view>
 * ```
 *
 *
 * ## AngularUI Router
 *
 * 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 team 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).

 * @param {string=} direction Which way to scroll. 'x' or 'y' or 'xy'. Default 'y'.
 * @param {boolean=} locking Whether to lock scrolling in one direction at a time. Useful to set to false when zoomed in or scrolling in two directions. Default true.
 * @param {boolean=} paging Whether to scroll with paging.
 * @param {expression=} on-refresh Called on pull-to-refresh, triggered by an {@link ionic.directive:ionRefresher}.
 * @param {expression=} on-scroll Called whenever the user scrolls.
 * @param {boolean=} scrollbar-x Whether to show the horizontal scrollbar. Default true.
 * @param {boolean=} scrollbar-y Whether to show the vertical scrollbar. Default true.

/**
 * @ngdoc directive
 * @name ionSideMenus
 * @module ionic
 * @delegate ionic.service:$ionicSideMenuDelegate
 * @restrict E
 *
 * @description
 * A container element for side menu(s) and the main content. Allows the left and/or right side menu
 * to be toggled by dragging the main content area side to side.
 *
 * To automatically close an opened menu, you can add the {@link ionic.directive:menuClose} attribute
 * directive. The `menu-close` attribute is usually added to links and buttons within
 * `ion-side-menu-content`, so that when the element is clicked, the opened side menu will
 * automatically close.
 *
 * By default, side menus are hidden underneath their side menu content and can be opened by swiping
 * the content left or right or by toggling a button to show the side menu. Additionally, by adding the
 * {@link ionic.directive:exposeAsideWhen} attribute directive to an
 * {@link ionic.directive:ionSideMenu} element directive, a side menu can be given instructions about
 * "when" the menu should be exposed (always viewable).
 *
 * ![Side Menu](http://ionicframework.com.s3.amazonaws.com/docs/controllers/sidemenu.gif)
 *
 * For more information on side menus, check out:
 *
 * - {@link ionic.directive:ionSideMenuContent}
 * - {@link ionic.directive:ionSideMenu}
 * - {@link ionic.directive:menuToggle}
 * - {@link ionic.directive:menuClose}
 * - {@link ionic.directive:exposeAsideWhen}
 *
 * @usage
 * To use side menus, add an `<ion-side-menus>` parent element,
 * an `<ion-side-menu-content>` for the center content,
 * and one or more `<ion-side-menu>` directives.
 *
 * ```html
 * <ion-side-menus>
 *   <!-- Center content -->
 *   <ion-side-menu-content ng-controller="ContentController">
 *   </ion-side-menu-content>
 *
 *   <!-- Left menu -->
 *   <ion-side-menu side="left">
 *   </ion-side-menu>
 *
 *   <!-- Right menu -->
 *   <ion-side-menu side="right">
 *   </ion-side-menu>
 * </ion-side-menus>
 * ```
 * ```js
 * function ContentController($scope, $ionicSideMenuDelegate) {
 *   $scope.toggleLeft = function() {
 *     $ionicSideMenuDelegate.toggleLeft();
 *   };
 * }
 * ```
 *
 * @param {bool=} enable-menu-with-back-views Determines whether the side menu is enabled when the
 * back button is showing. When set to `false`, any {@link ionic.directive:menuToggle} will be hidden,
 * and the user cannot swipe to open the menu. When going back to the root page of the side menu (the
 * page without a back button visible), then any menuToggle buttons will show again, and menus will be
 * enabled again.
 * @param {string=} delegate-handle The handle used to identify this side menu
 * with {@link ionic.service:$ionicSideMenuDelegate}.
 *

/**
 * @ngdoc directive
 * @name ionView
 * @module ionic
 * @restrict E
 * @parent ionNavView
 *
 * @description
 * A container for view content and any navigational and header bar information. When a view
 * enters and exists its parent {@link ionic.directive:ionNavView}, the view also emits view
 * information, such as its title, whether the back button should show or not, whether the
 * corresponding {@link ionic.directive:ionNavBar} should show or not, which transition the view
 * should use to animate, and which direction to animate.
 *
 * *Views are cached to improve performance.* When a view is navigated away from, its element is
 * left in the DOM, and its scope is disconnected from the `$watch` cycle. When navigating to a
 * view that is already cached, its scope is reconnected, and the existing element, which was
 * left in the DOM, becomes active again. This can be disabled, or the maximum number of cached
 * views changed in {@link ionic.directive:ionicConfig}, in the view's `$state` configuration, or
 * as an attribute on the view itself (see below).
 *
 * @usage
 * Below is an example where our page will load with a {@link ionic.directive:ionNavBar} containing
 * "My Page" as the title.
 *
 * ```html
 * <ion-nav-bar></ion-nav-bar>
 * <ion-nav-view>
 *   <ion-view view-title="My Page">
 *     <ion-content>
 *       Hello!
 *     </ion-content>
 *   </ion-view>
 * </ion-nav-view>
 * ```
 *
 * ## View LifeCycle and Events
 *
 * Views can be cached, which means *controllers normally only load once*, which may
 * affect your controller logic. To know when a view has entered or left, events
 * have been added that are emitted from the view's scope. These events also
 * contain data about the view, such as the title and whether the back button should
 * show. Also contained is transition data, such as the transition type and
 * direction that will be or was used.
 *
 * <table class="table">
 *  <tr>
 *   <td><code>$ionicView.loaded</code></td>
 *   <td>The view has loaded. This event only happens once per
 * view being created and added to the DOM. If a view leaves but is cached,
 * then this event will not fire again on a subsequent viewing. The loaded event
 * is good place to put your setup code for the view; however, it is not the
 * recommended event to listen to when a view becomes active.</td>
 *  </tr>
 *  <tr>
 *   <td><code>$ionicView.enter</code></td>
 *   <td>The view has fully entered and is now the active view.
 * This event will fire, whether it was the first load or a cached view.</td>
 *  </tr>
 *  <tr>
 *   <td><code>$ionicView.leave</code></td>
 *   <td>The view has finished leaving and is no longer the
 * active view. This event will fire, whether it is cached or destroyed.</td>
 *  </tr>
 *  <tr>
 *   <td><code>$ionicView.beforeEnter</code></td>
 *   <td>The view is about to enter and become the active view.</td>
 *  </tr>
 *  <tr>
 *   <td><code>$ionicView.beforeLeave</code></td>
 *   <td>The view is about to leave and no longer be the active view.</td>
 *  </tr>
 *  <tr>
 *   <td><code>$ionicView.afterEnter</code></td>
 *   <td>The view has fully entered and is now the active view.</td>
 *  </tr>
 *  <tr>
 *   <td><code>$ionicView.afterLeave</code></td>
 *   <td>The view has finished leaving and is no longer the active view.</td>
 *  </tr>
 *  <tr>
 *   <td><code>$ionicView.unloaded</code></td>
 *   <td>The view's controller has been destroyed and its element has been
 * removed from the DOM.</td>
 *  </tr>
 * </table>
 *
 * ## Caching
 *
 * Caching can be disabled and enabled in multiple ways. By default, Ionic will
 * cache a maximum of 10 views. You can optionally choose to disable caching at
 * either an individual view basis, or by global configuration. Please see the
 * _Caching_ section in {@link ionic.directive:ionNavView} for more info.
 *
 * @param {string=} view-title A text-only title to display on the parent {@link ionic.directive:ionNavBar}.
 * For an HTML title, such as an image, see {@link ionic.directive:ionNavTitle} instead.
 * @param {boolean=} cache-view If this view should be allowed to be cached or not.
 * Please see the _Caching_ section in {@link ionic.directive:ionNavView} for
 * more info. Default `true`
 * @param {boolean=} hide-back-button Whether to hide the back button on the parent
 * {@link ionic.directive:ionNavBar} by default.
 * @param {boolean=} hide-nav-bar Whether to hide the parent
 * {@link ionic.directive:ionNavBar} by default.
