// Description:
// Ported from Atlas to BES
//                      by Beijiang Liu 
 
//    The output will be stored in the transient event store so it can be
//    passed to the simulation.
// 
// AuthorList:
//         W. Seligman: Initial Code 08-Nov-2002,
//         based on work by M. Shapiro and I. Hinchliffe
//         adapted for the CosmicGun by S Bentvelsen
