  Name:         frontend.c
  Created by:   Stefan Ritt
 
  Contents:     Example Slow Control Frontend program. Defines two
                slow control equipments, one for a HV device and one
                for a multimeter (usually a general purpose PC plug-in
                card with A/D inputs/outputs. As a device driver,
                the "null" driver is used which simulates a device
                without accessing any hardware. The used class drivers
                cd_hv and cd_multi act as a link between the ODB and
                the equipment and contain some functionality like
                ramping etc. To form a fully functional frontend,
                the device driver "null" has to be replaces with
                real device drivers.
