/**
 * @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 better able to handle the user experience and
 * interactivity.
 *
 * Similarly, `<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.
 *
 * Along with the blur/focus events, `input` support all standard text input
 * events like `keyup`, `keydown`, `keypress`, `input`,etc. Any standard event
 * can be attached and will function as expected.
 *
 * @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>
 *     <ion-input type="tel" placeholder="Tel Input"></ion-input>
 *   </ion-item>
 *

/**
 * @name TextArea
 * @description
 *
 * `ion-textarea` 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>
