   * \ingroup joystick
   * \brief Class to translate input from the driver into higher-level features
   *
   * Raw driver input arrives for three elements: buttons, hats and axes. When
   * driver input is handled by this class, it translates the raw driver
   * elements into physical joystick features, such as buttons, analog sticks,
   * etc.
   *
   * A button map is used to translate driver primitives to controller features.
   * The button map has been abstracted away behind the IButtonMap
   * interface so that it can be provided by an add-on.
