 *
 * @description
 * The `<md-radio-group>` directive identifies a grouping
 * container for the 1..n grouped radio buttons; specified using nested
 * `<md-radio-button>` elements.
 *
 * The radio button uses the accent color by default. The primary color palette may be used with
 * the `md-primary` class.
 *
 * Note: `<md-radio-group>` and `<md-radio-button>` handle `tabindex` differently
 * than the native `<input type="radio">` controls. Whereas the native controls
 * force the user to tab through all the radio buttons, `<md-radio-group>`
 * is focusable and by default the `<md-radio-button>`s are not.
 *
 * @param {string} ng-model Assignable angular expression to data-bind to.
 * @param {string=} ng-change AngularJS expression to be executed when input changes due to user
 *    interaction.
 * @param {boolean=} md-no-ink If present, disables ink ripple effects.
 *
 * @usage

 * <md-radio-group ng-model="selected">
