 * @def REGISTER_MOTIONCONTROLLER_FACTORY(mType, name, MotionController_class)
 *
 * @brief   A macro that defines MotionController factory.
 *
 * The factories are registered to the CMotionControllerFactory which uses them to create MotionControllers.
 * To define a new type of MotionController it needs to derive from CMotionControllerBase and be registered.
 *
 * Example usage:
 *
 * \code{.cpp}
 * REGISTER_MOTIONCONTROLLER_FACTORY(PCI_8164_ADLINK, "8164", CMotionController_8164)
 * \endcode
 *
 * @param   mType       The MotionController type.
 * @param   MotionController_class  The class of the MotionController that the factory creates.
