/** @class CbmAddress
 ** @brief Base class for interfaces to the unique address
 ** @author V.Friese <v.friese@gsi.de>
 ** @version 1.0
 **
 ** CbmAddress is the base class for the concrete interfaces to the
 ** unique address, which is encoded in a 32-bit field (Int_t).
 ** The definition of this bit field is different for the various
 ** detector systems; common for all is that the first four bits are
 ** reserved for the system identifier.
