//  (Description)
//    B03Run Class is for accumulating scored quantities which is 
//  scored using G4MutiFunctionalDetector and G4VPrimitiveScorer.
//  Accumulation is done using G4THitsMap object.
//
//    The constructor B03Run(const std::vector<G4String> mfdName)
//  needs a vector filled with MultiFunctionalDetector names which
//  was assigned at instantiation of MultiFunctionalDetector(MFD).
//  Then B03Run constructor automatically scans primitive scorers
//  in the MFD, and obtains collectionIDs of all collections associated
//  to those primitive scorers. Futhermore, the G4THitsMap objects 
//  for accumulating during a RUN are automatically created too.
//  (*) Collection Name is same as primitive scorer name.
// 
//    The resultant information is kept inside B03Run objects as
//  data members.
//  std::vector<G4String> fCollName;            // Collection Name,
//  std::vector<G4int> fCollID;                 // Collection ID,
//  std::vector<G4THitsMap<G4double>*> fRunMap; // HitsMap for RUN.
//
//  The resualtant HitsMap objects are obtain using access method,
//  GetHitsMap(..).
