   * @param   {String}    name
   * this should be the name of the gesture, lowercase
   * it is also being used to disable/enable the gesture per instance config.
   *
   * @param   {Number}    [index=1000]
   * the index of the gesture, where it is going to be in the stack of gestures detection
   * like when you build an gesture that depends on the drag gesture, it is a good
   * idea to place it after the index of the drag gesture.
   *
   * @param   {Object}    [defaults={}]
   * the default settings of the gesture. these are added to the instance settings,
   * and can be overruled per instance. you can also add the name of the gesture,
   * but this is also added by default (and set to true).
   *
   * @param   {Function}  handler
   * this handles the gesture detection of your custom gesture and receives the
   * following arguments:
   *
   *      @param  {Object}    eventData
   *      event data containing the following properties:
   *          timeStamp   {Number}        time the event occurred
   *          target      {HTMLElement}   target element
   *          touches     {Array}         touches (fingers, pointers, mouse) on the screen
   *          pointerType {String}        kind of pointer that was used. matches ionic.Gestures.POINTER_MOUSE|TOUCH
   *          center      {Object}        center position of the touches. contains pageX and pageY
   *          deltaTime   {Number}        the total time of the touches in the screen
   *          deltaX      {Number}        the delta on x axis we haved moved
   *          deltaY      {Number}        the delta on y axis we haved moved
   *          velocityX   {Number}        the velocity on the x
   *          velocityY   {Number}        the velocity on y
   *          angle       {Number}        the angle we are moving
   *          direction   {String}        the direction we are moving. matches ionic.Gestures.DIRECTION_UP|DOWN|LEFT|RIGHT
   *          distance    {Number}        the distance we haved moved
   *          scale       {Number}        scaling of the touches, needs 2 touches
   *          rotation    {Number}        rotation of the touches, needs 2 touches *
   *          eventType   {String}        matches ionic.Gestures.EVENT_START|MOVE|END
   *          srcEvent    {Object}        the source event, like TouchStart or MouseDown *
   *          startEvent  {Object}        contains the same properties as above,
   *                                      but from the first touch. this is used to calculate
   *                                      distances, deltaTime, scaling etc
   *
   *      @param  {ionic.Gestures.Instance}    inst
   *      the instance we are doing the detection for. you can get the options from
   *      the inst.options object and trigger the gesture event by calling inst.trigger
   *
   *
   * Handle gestures
   * --------------------
   * inside the handler you can get/set ionic.Gestures.detectionic.current. This is the current
   * detection sessionic. It has the following properties
   *      @param  {String}    name
   *      contains the name of the gesture we have detected. it has not a real function,
   *      only to check in other gestures if something is detected.
   *      like in the drag gesture we set it to 'drag' and in the swipe gesture we can
   *      check if the current gesture is 'drag' by accessing ionic.Gestures.detectionic.current.name
   *
   *      readonly
   *      @param  {ionic.Gestures.Instance}    inst
   *      the instance we do the detection for
   *
   *      readonly
   *      @param  {Object}    startEvent
   *      contains the properties of the first gesture detection in this sessionic.
   *      Used for calculations about timing, distance, etc.
   *
   *      readonly
   *      @param  {Object}    lastEvent
   *      contains all the properties of the last gesture detect in this sessionic.
   *
   * after the gesture detection session has been completed (user has released the screen)
   * the ionic.Gestures.detectionic.current object is copied into ionic.Gestures.detectionic.previous,
   * this is usefull for gestures like doubletap, where you need to know if the
   * previous gesture was a tap
   *
   * options that have been set by the instance can be received by calling inst.options
   *
   * You can trigger a gesture event by calling inst.trigger("mygesture", event).
   * The first param is the name of your gesture, the second the event argument
   *
   *
   * Register gestures
   * --------------------
   * When an gesture is added to the ionic.Gestures.gestures object, it is auto registered
   * at the setup of the first ionic.Gestures instance. You can also call ionic.Gestures.detectionic.register
   * manually and pass your gesture object as a param

/**
 * @ngdoc page
 * @name tap
 * @module ionic
 * @description
 * On touch devices such as a phone or tablet, some browsers implement a 300ms delay between
 * the time the user stops touching the display and the moment the browser executes the
 * click. This delay was initially introduced so the browser can know whether the user wants to
 * double-tap to zoom in on the webpage.  Basically, the browser waits roughly 300ms to see if
 * the user is double-tapping, or just tapping on the display once.
 *
 * Out of the box, Ionic automatically removes the 300ms delay in order to make Ionic apps
 * feel more "native" like. Resultingly, other solutions such as
 * [fastclick](https://github.com/ftlabs/fastclick) and Angular's
 * [ngTouch](https://docs.angularjs.org/api/ngTouch) should not be included, to avoid conflicts.
 *
 * Some browsers already remove the delay with certain settings, such as the CSS property
 * `touch-events: none` or with specific meta tag viewport values. However, each of these
 * browsers still handle clicks differently, such as when to fire off or cancel the event
 * (like scrolling when the target is a button, or holding a button down).
 * For browsers that already remove the 300ms delay, consider Ionic's tap system as a way to
 * normalize how clicks are handled across the various devices so there's an expected response
 * no matter what the device, platform or version. Additionally, Ionic will prevent
 * ghostclicks which even browsers that remove the delay still experience.
 *
 * In some cases, third-party libraries may also be working with touch events which can interfere
 * with the tap system. For example, mapping libraries like Google or Leaflet Maps often implement
 * a touch detection system which conflicts with Ionic's tap system.
 *
 * ### Disabling the tap system
 *
 * To disable the tap for an element and all of its children elements,
 * add the attribute `data-tap-disabled="true"`.
 *
 * ```html
 * <div data-tap-disabled="true">
 *     <div id="google-map"></div>
 * </div>
 * ```
 *
 * ### Additional Notes:
 *
 * - Ionic tap  works with Ionic's JavaScript scrolling
 * - Elements can come and go from the DOM and Ionic tap doesn't keep adding and removing
 *   listeners
 * - No "tap delay" after the first "tap" (you can tap as fast as you want, they all click)
 * - Minimal events listeners, only being added to document
 * - Correct focus in/out on each input type (select, textearea, range) on each platform/device
 * - Shows and hides virtual keyboard correctly for each platform/device
 * - Works with labels surrounding inputs
 * - Does not fire off a click if the user moves the pointer too far
 * - Adds and removes an 'activated' css class
 * - Multiple [unit tests](https://github.com/driftyco/ionic/blob/master/test/unit/utils/tap.unit.js) for each scenario
 *

/*

 IONIC TAP
 ---------------
 - Both touch and mouse events are added to the document.body on DOM ready
 - If a touch event happens, it does not use mouse event listeners
 - On touchend, if the distance between start and end was small, trigger a click
 - In the triggered click event, add a 'isIonicTap' property
 - The triggered click receives the same x,y coordinates as as the end event
 - On document.body click listener (with useCapture=true), only allow clicks with 'isIonicTap'
 - Triggering clicks with mouse events work the same as touch, except with mousedown/mouseup
 - Tapping inputs is disabled during scrolling

/**
 * @ngdoc page
 * @name keyboard
 * @module ionic
 * @description
 * On both Android and iOS, Ionic will attempt to prevent the keyboard from
 * obscuring inputs and focusable elements when it appears by scrolling them
 * into view.  In order for this to work, any focusable elements must be within
 * a [Scroll View](http://ionicframework.com/docs/api/directive/ionScroll/)
 * or a directive such as [Content](http://ionicframework.com/docs/api/directive/ionContent/)
 * that has a Scroll View.
 *
 * It will also attempt to prevent the native overflow scrolling on focus,
 * which can cause layout issues such as pushing headers up and out of view.
 *
 * The keyboard fixes work best in conjunction with the
 * [Ionic Keyboard Plugin](https://github.com/driftyco/ionic-plugins-keyboard),
 * although it will perform reasonably well without.  However, if you are using
 * Cordova there is no reason not to use the plugin.
 *
 * ### Hide when keyboard shows
 *
 * To hide an element when the keyboard is open, add the class `hide-on-keyboard-open`.
 *
 * ```html
 * <div class="hide-on-keyboard-open">
 *   <div id="google-map"></div>
 * </div>
 * ```
 * ----------
 *
 * ### Plugin Usage
 * Information on using the plugin can be found at
 * [https://github.com/driftyco/ionic-plugins-keyboard](https://github.com/driftyco/ionic-plugins-keyboard).
 *
 * ----------
 *
 * ### Android Notes
 * - If your app is running in fullscreen, i.e. you have
 *   `<preference name="Fullscreen" value="true" />` in your `config.xml` file
 *   you will need to set `ionic.Platform.isFullScreen = true` manually.
 *
 * - You can configure the behavior of the web view when the keyboard shows by setting
 *   [android:windowSoftInputMode](http://developer.android.com/reference/android/R.attr.html#windowSoftInputMode)
 *   to either `adjustPan`, `adjustResize` or `adjustNothing` in your app's
 *   activity in `AndroidManifest.xml`. `adjustResize` is the recommended setting
 *   for Ionic, but if for some reason you do use `adjustPan` you will need to
 *   set `ionic.Platform.isFullScreen = true`.
 *
 *   ```xml
 *   <activity android:windowSoftInputMode="adjustResize">
 *
 *   ```
 *
 * ### iOS Notes
 * - If the content of your app (including the header) is being pushed up and
 *   out of view on input focus, try setting `cordova.plugins.Keyboard.disableScroll(true)`.
 *   This does **not** disable scrolling in the Ionic scroll view, rather it
 *   disables the native overflow scrolling that happens automatically as a
 *   result of focusing on inputs below the keyboard.
 *

 * 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);

 *
 * For example, if `retain` is called three times, the backdrop will be shown until `release`
 * is called three times.

/**
 * @ngdoc service
 * @name $ionicHistory
 * @module ionic
 * @description
 * $ionicHistory keeps track of views as the user navigates through an app. Similar to the way a
 * browser behaves, an Ionic app is able to keep track of the previous view, the current view, and
 * the forward view (if there is one).  However, a typical web browser only keeps track of one
 * history stack in a linear fashion.
 *
 * Unlike a traditional browser environment, apps and webapps have parallel independent histories,
 * such as with tabs. Should a user navigate few pages deep on one tab, and then switch to a new
 * tab and back, the back button relates not to the previous tab, but to the previous pages
 * visited within _that_ tab.
 *
 * `$ionicHistory` facilitates this parallel history architecture.

/**
 * @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

 *
 * 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'])

 *
 * 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.

 * @ngdoc directive
 * @restrict A
 * @name collectionRepeat
 * @module ionic
 * @codepen 7ec1ec58f2489ab8f359fa1a0fe89c15
 * @description
 * `collection-repeat` allows an app to show huge lists of items much more performantly than
 * `ng-repeat`.
 *
 * It renders into the DOM only as many items as are currently visible.
 *
 * This means that on a phone screen that can fit eight items, only the eight items matching
 * the current scroll position will be rendered.
 *
 * **The Basics**:
 *
 * - The data given to collection-repeat must be an array.
 * - If the `item-height` and `item-width` attributes are not supplied, it will be assumed that
 *   every item in the list has the same dimensions as the first item.
 * - Don't use angular one-time binding (`::`) with collection-repeat. The scope of each item is
 *   assigned new data and re-digested as you scroll. Bindings need to update, and one-time bindings
 *   won't.
 *
 * **Performance Tips**:
 *
 * - The iOS webview has a performance bottleneck when switching out `<img src>` attributes.
 *   To increase performance of images on iOS, cache your images in advance and,
 *   if possible, lower the number of unique images. We're working on [a solution](https://github.com/driftyco/ionic/issues/3194).
 *
 * @usage

 *
 * @param {expression} collection-repeat The expression indicating how to enumerate a collection,
 *   of the format  `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` or `album in artist.albums | orderBy:'name'`.
 * @param {expression=} item-width The width of the repeated element. The expression must return
 *   a number (pixels) or a percentage. Defaults to the width of the first item in the list.
 *   (previously named collection-item-width)
 * @param {expression=} item-height The height of the repeated element. The expression must return
 *   a number (pixels) or a percentage. Defaults to the height of the first item in the list.
 *   (previously named collection-item-height)
 * @param {number=} item-render-buffer The number of items to load before and after the visible
 *   items in the list. Default 3. Tip: set this higher if you have lots of images to preload, but
 *   don't set it too high or you'll see performance loss.
 * @param {boolean=} force-refresh-images Force images to refresh as you scroll. This fixes a problem
 *   where, when an element is interchanged as scrolling, its image will still have the old src
 *   while the new src loads. Setting this to true comes with a small performance loss.

 * @ngdoc directive
 * @name ionContent
 * @module ionic
 * @delegate ionic.service:$ionicScrollDelegate
 * @restrict E
 *
 * @description
 * The ionContent directive provides an easy to use content area that can be configured
 * to use Ionic's custom Scroll View, or the built in overflow scrolling of the browser.
 *
 * While we recommend using the custom Scroll features in Ionic in most cases, sometimes
 * (for performance reasons) only the browser's native overflow scrolling will suffice,
 * and so we've made it easy to toggle between the Ionic scroll implementation and
 * overflow scrolling.
 *
 * You can implement pull-to-refresh with the {@link ionic.directive:ionRefresher}
 * directive, and infinite scrolling with the {@link ionic.directive:ionInfiniteScroll}
 * directive.
 *
 * Be aware that this directive gets its own child scope. If you do not understand why this
 * is important, you can read [https://docs.angularjs.org/guide/scope](https://docs.angularjs.org/guide/scope).
 *
 * @param {string=} delegate-handle The handle used to identify this scrollView
 * with {@link ionic.service:$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.

/**
 * @ngdoc directive
 * @name ionInfiniteScroll
 * @module ionic
 * @parent ionic.directive:ionContent, ionic.directive:ionScroll
 * @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=} spinner The {@link ionic.directive:ionSpinner} to show while loading. The SVG
 * {@link ionic.directive:ionSpinner} is now the default, replacing rotating font icons.
 * @param {string=} icon The icon to show while loading. Default: 'ion-load-d'.  This is depreicated
 * in favor of the SVG {@link ionic.directive:ionSpinner}.
 * @param {boolean=} immediate-check Whether to check the infinite scroll bounds immediately on load.
 *
 * @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);
 *       $scope.$broadcast('scroll.infiniteScrollComplete');
 *     });
 *   };
 *
 *   $scope.$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>
 * ```

 * `menu-close` is an attribute directive that closes a currently opened side menu.
 * Note that by default, navigation transitions will not animate between views when

 * history stack, making the new page the root of the history stack. This is done
 * to replicate the user experience seen in most side menu implementations, which is
 * to not show the back button at the root of the stack and show only the
 * menu button. We recommend that you also use the `enable-menu-with-back-views="false"`
 * {@link ionic.directive:ionSideMenus} attribute when using the menuClose directive.
 *
 * @usage
 * Below is an example of a link within a side menu. Tapping this link would

 * Use nav buttons to set the buttons on your {@link ionic.directive:ionNavBar}
 * 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.

/**
 * @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 `$ionicView.enter`, may be useful.
 *
 * By default, when navigating back in the history, the "forward" views are removed from the cache.
 * If you navigate forward to the same view again, it'll create a new DOM element and controller
 * instance. Basically, any forward views are reset each time. This can be configured using the
 * {@link ionic.provider:$ionicConfigProvider}:
 *
 * ```js
 * $ionicConfigProvider.views.forwardCache(true);
 * ```
 *
 * #### Disable cache globally
 *
 * The {@link ionic.provider:$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 {boolean=} drag-content Whether the content can be dragged. Default true.
 * @param {boolean|number=} edge-drag-threshold Whether the content drag can only start if it is below a certain threshold distance from the edge of the screen.  Default false. Accepts three types of values:
   *  - If a non-zero number is given, that many pixels is used as the maximum allowed distance from the edge that starts dragging the side menu.
   *  - If true is given, the default number of pixels (25) is used as the maximum allowed distance.
   *  - If false or 0 is given, the edge drag threshold is disabled, and dragging from anywhere on the content is allowed.

 * @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.
 *
 * "Burger Icon" toggles can be added to the header with the {@link ionic.directive:menuToggle}
 * attribute directive. Clicking the toggle will open and close the side menu like the `menu-close`
 * directive. The side menu will automatically hide on child pages, but can be overridden with the
 * enable-menu-with-back-views attribute mentioned below.
 *
 * 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: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 ionSpinner
* @module ionic
* @restrict E
 *
 * @description
 * The `ionSpinner` directive provides a variety of animated spinners.
 * Spinners enables you to give your users feedback that the app is
 * processing/thinking/waiting/chillin' out, or whatever you'd like it to indicate.
 * By default, the {@link ionic.directive:ionRefresher} feature uses this spinner, rather
 * than rotating font icons (previously included in [ionicons](http://ionicons.com/)).
 * While font icons are great for simple or stationary graphics, they're not suited to
 * provide great animations, which is why Ionic uses SVG instead.
 *
 * Ionic offers ten spinners out of the box, and by default, it will use the appropriate spinner
 * for the platform on which it's running. Under the hood, the `ionSpinner` directive dynamically
 * builds the required SVG element, which allows Ionic to provide all ten of the animated SVGs
 * within 3KB.

 *
 * Each spinner uses SVG with SMIL animations, however, the Android spinner also uses JavaScript
 * so it also works on Android 4.0-4.3. Additionally, each spinner can be styled with CSS,
 * and scaled to any size.
 *
 *
 * @usage
 * The following code would use the default spinner for the platform it's running from. If it's neither
 * iOS or Android, it'll default to use `ios`.
 *
 * ```html
 * <ion-spinner></ion-spinner>
 * ```
 *
 * By setting the `icon` attribute, you can specify which spinner to use, no matter what
 * the platform is.
 *
 * ```html
 * <ion-spinner icon="spiral"></ion-spinner>
 * ```
 *
 * ## Spinner Colors
 * Like with most of Ionic's other components, spinners can also be styled using
 * Ionic's standard color naming convention. For example:
 *
 * ```html
 * <ion-spinner class="spinner-energized"></ion-spinner>
 * ```
 *
 *
 * ## Styling SVG with CSS
 * One cool thing about SVG is its ability to be styled with CSS! Some of the properties
 * have different names, for example, SVG uses the term `stroke` instead of `border`, and
 * `fill` instead of `background-color`.
 *
 * ```css
 * .spinner svg {
 *   width: 28px;
 *   height: 28px;
 *   stroke: #444;
 *   fill: #444;
 * }
 * ```

/**
 * @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 `$watch` cycle. When navigating to a
 * view that is already cached, its scope is reconnected, and the existing element, which was
 * left in the DOM, becomes active again. This can be disabled, or the maximum number of cached
 * views changed in {@link ionic.provider:$ionicConfigProvider}, 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.
