GSI Properties

The following properties of the GSI copntrol system should be provided, compatible to the existing stepper motors. Only for single motors 'true' devices (which implement properties to move motors) must be provided. For slits, only devices will be provided which provide to read back some device information (including device status) but will not support motor movement.
