Hi all,

I've committed a new brat version: 2.3.5 and tagged it BRAT-2-3-5

Many updates and a few changes:

* brat/scripts/calib/
   updated CrashPed.C so that you can calibrate directly as bramreco
   added options to enable/disable detectors
   removed obsolete files

* brat/scripts/calib/tof and bb 
   updated all scripts so that they can run over any directory containing 
   sequences run00xxxseqxxx.root + added options to enable/disable mrs, 
   ffs or bfs for the tof calibration.

These scripts can be used by anyone to perform calibrations. I've finished 
some doc on how to do it. I'll post it when I correct typos and other 
small errors.

* brat/data/track
   updated class BrBfsTrack, removed useless members (incremented class 
   version number) and made useless methods inactive (in order not to 
   break codes of other users by simply removing these methods)

   introduced new class (hopefully temporary) BrFsTrack which combines FFS 
   and BFS tracks (cf. module)

* brat/modules/track/combine
   updated BrBfsTrackingModule: added method SetExtendD4Match(bool) to 
   allow the extension of D4 matched tracks to D3 when no D3 matched 
   tracks are available for BFS reconstruction. The virtual matched track 
   created then has a T3 detector track as front track (NOT T2) 

   added BrFsTrackingModule, that matched FFS and BFS when it can:
   -> when no FFS tracks, BFS tracks are simply swimmed back to the vertex
   -> when FFS tracks:
         --> if BFS tracks used T2, simply check FFS tracks with same T2
         --> if BFS tracks used T3, check which H1 slat is pointed and 
             match FFS and BFS tracks pointing to the same slat (a bit too 
             simple, should add some more criteria maybe)
         --> the rest of BFS tracks are simply swimmed back to the vertex  		
   

   How to use it: in your bratmain script, do the following
  	
   BrFsTrackingModule* fsmod = new BrFsTrackingModule("FS", "FS Tracker");
   mainModule->AddModule(fsmod);

   BrFfsTrackingModule* ffsmod = fsmod->GetFfsModule();		
   ffsmod-> ...
   ...

   BrBfsTrackingModule* bfsmod = fsmod->GetBfsModule();
   bfsmod-> ...	
   ...


* brat/modules/calib/tof
              /rdo
              /pid

   updated all tof modules dealing with H2 so that they pick up FS tracks 
   instead of BFS tracks.

* brat/modules/util 
   updated tof-track matching modules (minor changes) 
   
 
* configure.in: bumped version number to 2.3.5


That's all folks.

Ciao
Djam

PS: For those running the BrBfsTrackingModule for physics analysis, don't 
forget the cleanup methods to remove duplicates of matched tracks using 
the same T4 track (T2-T4 and T3-T4)
