  /**

   * @module material.components.checkbox
   * @restrict E
   *
   * @description
   * The checkbox directive is used like the normal [angular checkbox](https://docs.angularjs.org/api/ng/input/input%5Bcheckbox%5D).
   *
   * As per the [material design spec](http://www.google.com/design/spec/style/color.html#color-ui-color-application)
   * the checkbox is in the accent color by default. The primary color palette may be used with
   * the `md-primary` class.
   *
   * @param {string} ng-model Assignable angular expression to data-bind to.
   * @param {string=} name Property name of the form under which the control is published.
   * @param {expression=} ng-true-value The value to which the expression should be set when selected.
   * @param {expression=} ng-false-value The value to which the expression should be set when not selected.
   * @param {string=} ng-change Angular expression to be executed when input changes due to user interaction with the input element.
   * @param {boolean=} md-no-ink Use of attribute indicates use of ripple ink effects
   * @param {string=} aria-label Adds label to checkbox for accessibility.
   *     Defaults to checkbox's text. If no default text is found, a warning will be logged.
   * @param {expression=} md-indeterminate This determines when the checkbox should be rendered as 'indeterminate'.
   *     If a truthy expression or no value is passed in the checkbox renders in the md-indeterminate state.
   *     If falsy expression is passed in it just looks like a normal unchecked checkbox.
   *     The indeterminate, checked, and unchecked states are mutually exclusive. A box cannot be in any two states at the same time.
   *     When a checkbox is indeterminate that overrides any checked/unchecked rendering logic.
   *

   * <md-checkbox md-no-ink ng-model="hasInk" aria-label="No Ink Effects">
