+/**
+ * @name Alert
+ * @description
+ * An Alert is a dialog that presents users with either information, or used
+ * to receive information from the user using inputs. An alert appears on top
+ * of the app's content, and must be manually dismissed by the user before
+ * they can resume interaction with the app.
+ *
+ * An alert is created from an array of `buttons` and optionally an array of
+ * `inputs`. Each button includes properties for its `text`, and optionally a
+ * `handler`. If a handler returns `false` then the alert will not be dismissed.
+ * An alert can also optionally have a `title`, `subTitle` and `body`.
+ *
+ * All buttons will show up in the order they have been added to the `buttons`
+ * array, from left to right. Note: The right most button (the last one in the
+ * array) is the main button.
+ *
+ * Alerts can also include inputs whos data can be passed back to the app.
+ * Inputs can be used to prompt users for information.
+ *
+ * Its shorthand is to add all the alert's options from within the
+ * `Alert.create(opts)` first argument. Otherwise the alert's
+ * instance has methods to add options, such as `setTitle()` or `addButton()`.
+ *
+ * @usage
+ * ```ts
+ * constructor(nav: NavController) {
+ *   this.nav = nav;
+ * }
+ *
+ * presentAlert() {
+ *   let alert = Alert.create({
+ *     title: 'Low battery',
+ *     subTitle: '10% of battery remaining',
+ *     buttons: ['Dismiss']
+ *   });
+ *   this.nav.present(alert);
+ * }
+ *
+ * presentConfirm() {
+ *   let alert = Alert.create({
+ *     title: 'Confirm purchase',
+ *     body: 'Do you want to buy this book?',
+ *     buttons: [
+ *       {
+ *         text: 'Cancel',
+ *         handler: () => {

+ *           console.log('Buy clicked');
+ *         }
