 * \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.
