// Description: Relation class
//
// changes:
// 21 Aug 2000 (TG) creation
// 13 Sep 2000 (TG) added MassC member
// 20 Okt 2000 (TG) #include VtVassC_list.hh added, changed type of massc
//                  from MassC* to MassC_v
// 14 Nov 2000 (TG) added getTrack(), getVertex(), getKalman() member functions,
//                  hide reference members in case of CINT (CINT limitation)
