/**
 * @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, if the back button should show or not, if
 * the corresponding {@link ionic.directive:ionNavBar} should show or not, which transition the view
 * should use to animate, and what 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 cycle. When navigating
 * to a view which is already cached, its scope is reconnected, and the existing element which
 * was left in the DOM becomes the active view. Config variables can be used to disable this
 * feature, or change the maximum number of views which can be cached.
 *
 * @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>
 * ```
 *
 * @param {string=} view-title The title to display on the parent {@link ionic.directive:ionNavBar}.
 * @param {boolean=} cache-view If this view should be allowed to be cached or not. 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.
