// $Log: BrTofCalModule.h,v $
// Revision 1.7  2002/03/21 15:04:25  ouerdane
// added fComment member to base class module and method SetComment so that the user can set comments about the calibration at commit time. Removed mean momentum stuff in slewing cal module
//
// Revision 1.6  2001/11/07 10:30:55  ouerdane
// updated module for H2 cal. and PID
//
// Revision 1.5  2001/11/05 06:59:44  ouerdane
// changed to deal with new track classes and fixed some bugs
//
// Revision 1.4  2001/10/20 00:07:17  ouerdane
// removed useless old member fNoPanel
//
// Revision 1.3  2001/10/02 01:53:28  ouerdane
// Added SetSaveAscii, SetLoadAscii, SetCommitAscii and updated the way parameters are tagged for Use
//
// Revision 1.2  2001/07/31 09:21:32  ouerdane
// Removed all references to a TList member, replaced
// by histogram members, declare ntuple if fNtuple is true (set
// via SetNtuple)
//
// Revision 1.1.1.1  2001/06/21 14:55:05  hagel
// Initial revision of brat2
//
// Revision 1.3  2001/06/21 12:59:56  ouerdane
// See implementation files last log
//
// Revision 1.2  2001/06/20 09:12:29  ouerdane
// Changed value of BrTofCalibration::kCalException to 999999
// Removed the old exception in BrTofCalModule
//
// Revision 1.1  2001/06/19 12:44:48  ouerdane
// Added calibration classes and reconstruction classes.
// Brat compiles but these classes haven't been tested in this
// context. Be careful if you use them before I (DO) check if
// all is ok.
//
// Revision 1.1  2001/06/01 10:07:07  ouerdane
// Made a base class for TOF calibration modules.
// It basically contains the calibration and parameter objects
// and methods for reading from or saving to ascii files
//
//
