   * @name Toggle
   * @description
   * A toggle technically is the same thing as an HTML checkbox input,
   * except it looks different and is easier to use on a touch device.
   * Toggles can also have colors assigned to them, by adding any color
   * attribute.
   *
   * See the [Angular 2 Docs](https://angular.io/docs/ts/latest/guide/forms.html)
   * for more info on forms and inputs.
   *
   * @usage
   * ```html
   *
   *  <ion-list>
   *
   *    <ion-item>
   *      <ion-label>Pepperoni</ion-label>
   *      <ion-toggle [(ngModel)]="pepperoni"></ion-toggle>
   *    </ion-item>
   *
   *    <ion-item>
   *      <ion-label>Sausage</ion-label>
   *      <ion-toggle [(ngModel)]="sausage" disabled="true"></ion-toggle>
   *    </ion-item>
   *
   *    <ion-item>
   *      <ion-label>Mushrooms</ion-label>
