/**
 * @name NavPush
 * @description
 * Directive to declaratively push a new page to the current nav
 * stack.
 *
 * @usage
 * ```html
 * <button ion-button [navPush]="pushPage"></button>
 * ```
 *
 * To specify parameters you can use array syntax or the `navParams`
 * property:
 *
 * ```html
 * <button ion-button [navPush]="pushPage" [navParams]="params">Go</button>
 * ```
 *
 * Where `pushPage` and `params` are specified in your component,
 * and `pushPage` contains a reference to a
 * component you would like to push:
 *
 * ```ts
 * import { LoginPage } from './login';
 *
 * @Component({
 *   template: `<button ion-button [navPush]="pushPage" [navParams]="params">Go</button>`
 * })
 * class MyPage {
 *   pushPage: any;
 *   params: Object;
 *   constructor(){
 *     this.pushPage = LoginPage;
 *     this.params = { id: 42 };
 *   }
 * }
 * ```
 *
