  		 * automatically call {{#crossLink "BitmapAnimation/gotoAndStop"}}{{/crossLink}} or {{#crossLink "BitmapAnimation/gotoAndPlay"}}{{/crossLink}},
  		 * to the respective animation labels, add a pointer cursor, and allows the user to define a hit state frame.
  		 *
  		 * The ButtonHelper instance does not need to be added to the stage, but a reference should be maintained to prevent
  		 * garbage collection.
  		 *
  		 * @example
  		 *      var helper = new createjs.ButtonHelper(myInstance, "out", "over", "down", false, myInstance, "hit");
  		 *
  		 * @param {BitmapAnimation|MovieClip} target The instance to manage.
  		 * @param {String} [outLabel="out"] The label or animation to go to when the user rolls out of the button.
  		 * @param {String} [overLabel="over"] The label or animation to go to when the user rolls over the button.
  		 * @param {String} [downLabel="down"] The label or animation to go to when the user presses the button.
  		 * @param {Boolean} [play=false] If the helper should call "gotoAndPlay" or "gotoAndStop" on the button when changing
  		 * states.
  		 * @param {DisplayObject} [hitArea] An optional item to use as the hit state for the button. If this is not defined,
  		 * then the button's visible states will be used instead. Note that the same instance as the "target" argument can be
  		 * used for the hitState.
  		 * @param {String} [hitLabel] The label or animation on the hitArea instance that defines the hitArea bounds. If this is
  		 * null, then the default state of the hitArea will be used.
