/** CbmShieldGenerator
 *@author V.Friese  <v.friese@gsi.de>
 *@since 15.09.06
 *@version 1.0
 *
 ** The CbmShieldGenerator is similar to the CbmAsciiGenerator. It uses the
 ** ASCII output of the SHIELD code as input for simulation.
 ** The format of the event header is:
 ** event nr.; number of particles; beam momentum; impact parameter
 ** followed by a line for each particle of the format
 ** PID; A; Z; px; py; pz
 ** The PID must be given as for GEANT3. For ions, it is 1000. The total
 ** momentum is required, not momentum per nucleon.
