/**
 * @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 Docs](https://angular.io/docs/ts/latest/guide/forms)
 * 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>
 *      <ion-toggle [(ngModel)]="mushrooms"></ion-toggle>
 *    </ion-item>
 *
 *  </ion-list>
