   * @name Input
   * @description
   *
   * `ion-input` is meant for text type inputs only, such as `text`,
   * `password`, `email`, `number`, `search`, `tel`, and `url`. Ionic
   * still uses an actual `<input type="text">` HTML element within the
   * component, however, with Ionic wrapping the native HTML input
   * element it's able to better handle the user experience and
   * interactivity.
   *
   * Similarily, `<ion-textarea>` should be used in place of `<textarea>`.
   *
   * An `ion-input` is **not** used for non-text type inputs, such as a
   * `checkbox`, `radio`, `toggle`, `range`, `select`, etc.
   *
   *
   * @usage
   * ```html
   * <ion-list>
   *   <ion-item>
   *     <ion-label color="primary">Inline Label</ion-label>
   *     <ion-input placeholder="Text Input"></ion-input>
   *   </ion-item>
   *
   *   <ion-item>
   *     <ion-label color="primary" fixed>Fixed Label</ion-label>

  /**
   * @name TextArea
   * @description
   *
   * `ion-textarea` is is used for multi-line text inputs. Ionic still
   * uses an actual `<textarea>` HTML element within the component;
   * however, with Ionic wrapping the native HTML text area element, Ionic
   * is able to better handle the user experience and interactivity.
   *
   * Note that `<ion-textarea>` must load its value from the `value` or
   * `[(ngModel)]` attribute. Unlike the native `<textarea>` element,
   * `<ion-textarea>` does not support loading its value from the
   * textarea's inner content.
   *
   * When requiring only a single-line text input, we recommend using
   * `<ion-input>` instead.
   *
   * @usage
   * ```html
   *  <ion-item>
   *    <ion-label>Comments</ion-label>
   *    <ion-textarea></ion-textarea>
   *  </ion-item>
   *
   *  <ion-item>
   *    <ion-label stacked>Message</ion-label>
   *    <ion-textarea [(ngModel)]="msg"></ion-textarea>
