// $Log: BrBfsTofMatchingModule.h,v $
// Revision 1.6  2002/04/09 02:10:07  ouerdane
// updated to reflect latest changes in BrBfsTrack
//
// Revision 1.5  2001/11/07 10:32:14  ouerdane
// updated matching module for H2 recontruction and PID
//
// Revision 1.4  2001/11/05 07:11:40  ouerdane
// changed FFS to Ffs, BFS to Bfs, MRS to Mrs. Fixed bugs in BFS module
//
// Revision 1.3  2001/10/07 13:36:49  ouerdane
// Allowed to set true or false the use of H1 even if the arms are aligned
//
// Revision 1.2  2001/10/02 20:20:40  ouerdane
// remove member fNoPanels and setter method since it is now part of the
// tof detector parameter class.
// Corrected errors due to fast rewriting of the modules. should be ok now.
//
// Revision 1.1  2001/10/02 02:05:25  ouerdane
// Added modules combining and saving Tracks and Tof hits
//
//
