// A pure virtual class that represents a generic Bes sensitive
// Detector. Bes subsystems should inherit from this class when
// implementing their hit scoring.
//
// Subsystems may optionally override the following methods:
//         BeginOfEvent
//         EndOfEvent
//         BeginOfTrack
//         EndOfTrack
// The following utility methods are provided:
//         GetMonteCarloId
//
// Chronological sequence:
//
//       For each event:
//               call BeginOfTruthEvent()
//               For each track:
//                      call BeginOfTrack()
//                      processHits()
//                      call EndOfTrack()
//               call EndOfTruthEvent()
//
