/**
 * @name Refresher
 * @description
 * The Refresher provides pull-to-refresh functionality on a content component.
 * Place the `ion-refresher` as the first child of your `ion-content` element.
 *
 * Pages can then listen to the refresher's various output events. The
 * `refresh` output event is fired when the user has pulled down far
 * enough to kick off the refreshing process. Once the async operation
 * has completed and the refreshing should end, call `complete()`.
 *
 * Note: Do not wrap the `ion-refresher` in a `*ngIf`. It will not render
 * properly this way. Please use the `enabled` property instead to
 * display or hide the refresher.
 *
 * @usage
 * ```html
 * <ion-content>
 *
 *   <ion-refresher (ionRefresh)="doRefresh($event)">
 *     <ion-refresher-content></ion-refresher-content>
 *   </ion-refresher>
 *
 * </ion-content>
 * ```
 *
 * ```ts
 * @Component({...})
 * export class NewsFeedPage {
 *
 *   doRefresh(refresher) {
 *     console.log('Begin async operation', refresher);
 *
 *     setTimeout(() => {
 *       console.log('Async operation has ended');
 *       refresher.complete();
 *     }, 2000);
 *   }
 *
 * }
 * ```
 *
 *
 * ## Refresher Content
 *
 * By default, Ionic provides the pulling icon and refreshing spinner that
 * looks best for the platform the user is on. However, you can change the
 * default icon and spinner, along with adding text for each state by
 * adding properties to the child `ion-refresher-content` component.
 *
 *  ```html
 *  <ion-content>
 *
 *    <ion-refresher (ionRefresh)="doRefresh($event)">
 *      <ion-refresher-content
 *        pullingIcon="arrow-dropdown"
 *        pullingText="Pull to refresh"
 *        refreshingSpinner="circles"
 *        refreshingText="Refreshing...">
 *      </ion-refresher-content>
 *    </ion-refresher>
 *
 *  </ion-content>
 *  ```
 *
 *
 * ## Further Customizing Refresher Content
 *
 * The `ion-refresher` component holds the refresh logic.
 * It requires a child component in order to display the content.
 * Ionic uses `ion-refresher-content` by default. This component
 * displays the refresher and changes the look depending
 * on the refresher's state. Separating these components
 * allows developers to create their own refresher content
 * components. You could replace our default content with
 * custom SVG or CSS animations.

     * - `ready` - The user has pulled down the refresher far enough that if they let go, it'll begin the `refreshing` state.
