+TreeC created once per event (M.Masera)
+
+Revision 1.70 2002/05/10 22:28:30 nilsen
+Changes by Massimo Masera to allow the TTree of clusters to be written to a
+file otherthan the one with digits in it.
+
+Revision 1.69 2002/05/05 21:06:55 nilsen
+Added GetSimulationMoel, and fixed up SetDefaultSimulation to do the
+proper initilization when a simulation has already been defined.
+
+Revision 1.68 2002/05/02 18:51:53 nilsen
+AliITS.h
+ Method MakeBranchR has now a second argument, with a default value:
+ Option_t *opt=" ". Opt="Fast" is to create a separate branch
+ for fast points in TreeR
+ New method MakeBranchRF: it a separate branch in TreeR for Fast Points
+
+AliITS.cxx
+1) TTree->Write() replaced with TTree->AutoSave for TreeS, TreeD and
+ TreeR
