/**
 * @description
 * A radio button is a button that can be either checked or unchecked. A user can tap
 * the button to check or uncheck it. It can also be checked from the template using
 * the `checked` property.
 *
 * Use an element with a `radio-group` attribute to group a set of radio buttons. When
 * radio buttons are inside a [radio group](../RadioGroup), exactly one radio button
 * in the group can be checked at any time. If a radio button is not placed in a group,
 * they will all have the ability to be checked at the same time.
 *
 * See the [Angular Forms Docs](https://angular.io/docs/ts/latest/guide/forms.html) for
 * more information on forms and input.
 *
 * @usage
 * ```html
 * <ion-list radio-group [(ngModel)]="relationship">
 *   <ion-item>
 *     <ion-label>Friends</ion-label>
 *     <ion-radio value="friends" checked></ion-radio>
 *   </ion-item>
 *   <ion-item>
 *     <ion-label>Family</ion-label>
 *     <ion-radio value="family"></ion-radio>
 *   </ion-item>
 *   <ion-item>
 *     <ion-label>Enemies</ion-label>
 *     <ion-radio value="enemies" [disabled]="isDisabled"></ion-radio>
 *   </ion-item>
 * </ion-list>
