BRAT 2.4.5 - BrTileParameters

//______________________________________________________________________
//
// BrTileParameters is a BRAHMS data class providing storage
// and access function for MultTile specific digitization parameters. 
// This allows modification of the BrDetectorParams content by the 
// user.

// $Log: BrTileParameters.cxx,v $
// Revision 1.1.1.1  2001/06/21 14:55:00  hagel
// Initial revision of brat2
//
// Revision 1.5  2001/05/31 01:47:14  cholm
// Second rewamp of this directory.  All RDO modules use the common
// BrMultRdoModule, and they both write BrMultRdo Objects.  Also introduced
// ABC for Br[Tile|Si][Parameters|Calibration] since they have a lot in common,
// and the code can be made more efficient this way.
//
// A possible further thing to do, is to make an ABC for the CentModules, and
// the corresponding calibration modules, since they are very VERY similar.
// However, the current module BrMultCentModule is in the way.  Need to talk
// to Steve about that.
//
// Revision 1.4  2001/05/03 18:45:54  cholm
// Fixed a few superflous warnings, and uninitialised array in BrTileParameters
//
// Revision 1.3  2001/04/02 01:18:37  sanders
// BrRdoMult and BrRdoModuleMult reinstated.  These files develop the joint
// Si+Tile multiplicity.  BrRdoModuleMult now gets it parameters from the
// BrTileRdoModule and BrSiRdoModule classes and is a friend of these classes.
//
// Revision 1.2  2001/01/31 17:34:19  cholm
// Corrected bug in BrTileParameters when readin from DetectorParameters.txt
//
// Revision 1.1  2001/01/29 20:14:21  cholm
// Changed name of BrDetectorParamsMultTile to BrTileParameters. See also
// corresponding log message for BrSiParameters.
//
// Revision 1.4  2000/08/17 14:50:43  hito
// *** empty log message ***
//
// Revision 1.3  2000/07/26 22:08:37  hito
// Mapping of digitization for si and tile were changed to reflect the raw data
// and the change in gbrahms.
//
// Revision 1.2  2000/03/21 21:22:20  cholm
// Several changes: A few hacks where needed to compile on Digital Unix, noticably in my - Christian Holm - classes for the DB and Exceptions. Proberly still need to do something to some of Konstantins stuff. Also, I removed a lot of warnings fromt the compiler, by teddying up the code. Several places, old C-style indecies in for loops were assumed. Corrected. Unused variables have been commented out.
//
// Revision 1.1  1999/11/30 22:22:15  videbaek
// dded new class to digitize Multiplicity tiles.
