   * @description
   * The `<md-slider>` component allows the user to choose from a range of
   * values.
   *
   * As per the [material design spec](http://www.google.com/design/spec/style/color.html#color-ui-color-application)
   * the slider is in the accent color by default. The primary color palette may be used with
   * the `md-primary` class.
   *
   * It has two modes: 'normal' mode, where the user slides between a wide range
   * of values, and 'discrete' mode, where the user slides between only a few
   * select values.
   *
   * To enable discrete mode, add the `md-discrete` attribute to a slider,
   * and use the `step` attribute to change the distance between
   * values the user is allowed to pick.
   *
   * @usage
   * <h4>Normal Mode</h4>
   * <hljs lang="html">
   * <md-slider ng-model="myValue" min="5" max="500">
   * </md-slider>
   * </hljs>
   * <h4>Discrete Mode</h4>
   * <hljs lang="html">
   * <md-slider md-discrete ng-model="myDiscreteValue" step="10" min="10" max="130">
   * </md-slider>
   * </hljs>
   *
   * @param {boolean=} md-discrete Whether to enable discrete mode.
   * @param {number=} step The distance between values the user is allowed to pick. Default 1.
   * @param {number=} min The minimum value the user is allowed to pick. Default 0.
   * @param {number=} max The maximum value the user is allowed to pick. Default 100.
