/**
 * @name Popover
 * @description
 * A Popover is a dialog that appears on top of the current page.
 * It can be used for anything, but generally it is used for overflow
 * actions that don't fit in the navigation bar.
 *
 * ### Creating
 * A popover can be created by calling the `create` method. The view
 * to display in the popover should be passed as the first argument.
 * Any data to pass to the popover view can optionally be passed in
 * the second argument. Options for the popover can optionally be
 * passed in the third argument. See the [create](#create) method
 * below for all available options.
 *
 * ### Presenting
 * To present a popover, call the `present` method on the [NavController](../../nav/NavController).
 * The first argument passed to the `present` should be the popover. In order
 * to position the popover relative to the element clicked, the event needs to be
 * passed as the second argument. If the event is not passed, the popover will be
 * positioned in the center of the current view. See the [usage](#usage) section for
 * an example of passing this event.
 *
 * ### Dismissing
 * To dismiss the popover after creation, call the `dismiss()` method on the
 * `Popover` instance. The popover can also be dismissed from within the popover's
 * view by calling the `dismiss()` method on the [ViewController](../../nav/ViewController).
 * The `onDismiss` function can be called to perform an action after the popover
 * is dismissed. The popover will dismiss when the backdrop is clicked, but this
 * can be disabled by setting `enableBackdropDismiss` to `false` in the popover
 * options.
 *
 * > Note that after the component is dismissed, it will not be usable anymore and
 * another one must be created. This can be avoided by wrapping the creation and
 * presentation of the component in a reusable function as shown in the [usage](#usage)
 * section below.
 *
 * @usage
 *
 * To open a popover on the click of a button, pass `$event` to the method
 * which creates and presents the popover:
 *
 * ```html
 * <button (click)="presentPopover($event)">
 *   <ion-icon name="more"></ion-icon>
 * </button>
 * ```
 *
 * ```ts
 * @Component({})
 * class MyPage {
 *   constructor(private nav: NavController) {}
 *
 *   presentPopover(myEvent) {
 *     let popover = Popover.create(PopoverPage);
 *     this.nav.present(popover, {
 *       ev: myEvent
 *     });
 *   }
 * }
 * ```
 *
 * The `PopoverPage` will display inside of the popover, and
 * can be anything. Below is an example of a page with items
 * that close the popover on click.
 *
 * ```ts
 * @Component({
 *   template: `
 *     <ion-list>
 *       <ion-list-header>Ionic</ion-list-header>
 *       <button ion-item (click)="close()">Learn Ionic</button>
 *       <button ion-item (click)="close()">Documentation</button>
 *       <button ion-item (click)="close()">Showcase</button>
 *       <button ion-item (click)="close()">GitHub Repo</button>
 *     </ion-list>
 *   `
 * })
 * class PopoverPage {
 *   constructor(private viewCtrl: ViewController) {}
 *
 *   close() {
 *     this.viewCtrl.dismiss();
 *   }
 * }
 * ```

 * A Popover is a dialog that appears on top of the current page.

 * ### Creating
 * A popover can be created by calling the `create` method. The view

 * Any data to pass to the popover view can optionally be passed in
 * the second argument. Options for the popover can optionally be

 * The first argument passed to the `present` should be the popover. In order
 * to position the popover relative to the element clicked, the event needs to be
 * passed as the second argument. If the event is not passed, the popover will be
