/**
 * @name ModalController
 * @description
 * A Modal is a content pane that goes over the user's current page.
 * Usually it is used for making a choice or editing an item. A modal uses the
 * `NavController` to
 * {@link /docs/v2/api/components/nav/NavController/#present present}
 * itself in the root nav stack. It is added to the stack similar to how
 * {@link /docs/v2/api/components/nav/NavController/#push NavController.push}
 * works.
 *
 * When a modal (or any other overlay such as an alert or actionsheet) is
 * "presented" to a nav controller, the overlay is added to the app's root nav.
 * After the modal has been presented, from within the component instance The
 * modal can later be closed or "dismissed" by using the ViewController's
 * `dismiss` method. Additionally, you can dismiss any overlay by using `pop`
 * on the root nav controller.
 *
 * Data can be passed to a new modal through `Modal.create()` as the second
 * argument. The data can then be accessed from the opened page by injecting
 * `NavParams`. Note that the page, which opened as a modal, has no special
 * "modal" logic within it, but uses `NavParams` no differently than a
 * standard page.
 *
 * @usage
 * ```ts
 * import { ModalController, NavParams } from 'ionic-angular';
 *
 * @Component(...)
 * class HomePage {
 *
 *  constructor(private modalCtrl: ModalController) {
 *
 *  }
 *
 *  presentProfileModal() {
 *    let profileModal = this.modalCtrl.create(Profile, { userId: 8675309 });
 *    profileModal.present();
 *  }
 *
 * }
 *
 * @Component(...)
 * class Profile {
 *
 *  constructor(params: NavParams) {
 *    console.log('UserId', params.get('userId'));
 *  }
 *
 * }
 * ```

 * | enableBackdropDismiss |`boolean`   | Whether the popover should be dismissed by tapping the backdrop. Default true.                                   |
 *
 * A modal can also emit data, which is useful when it is used to add or edit
 * data. For example, a profile page could slide up in a modal, and on submit,
 * the submit button could pass the updated profile data, then dismiss the
 * modal.
 *
 * ```ts
 * import { Component } from '@angular/core';
 * import { ModalController, ViewController } from 'ionic-angular';
 *
 * @Component(...)
 * class HomePage {
 *
 *  constructor(private modalCtrl: ModalController) {
 *
 *  }
 *
 *  presentContactModal() {
 *    let contactModal = this.modalCtrl.create(ContactUs);
 *    contactModal.present();
 *  }
 *
 *  presentProfileModal() {
 *    let profileModal = this.modalCtrl.create(Profile, { userId: 8675309 });
 *    profileModal.onDidDismiss(data => {
 *      console.log(data);
 *    });
 *    profileModal.present();
 *  }
 *
 * }
 *
 * @Component(...)
 * class Profile {
 *
 *  constructor(private viewCtrl: ViewController) {
 *
 *  }
 *
 *  dismiss() {
 *    let data = { 'foo': 'bar' };
 *    this.viewCtrl.dismiss(data);
 *  }
