+Revision 1.65 2001/11/27 16:27:28 nilsen
+Adding AliITSDigitizer class to do merging and digitization . Based on the
+TTask method. AliITSDigitizer class added to the Makefile and ITSLinkDef.h
+file. The following files required minor changes. AliITS, added functions
+SetHitsAddressBranch, MakeBranchInTreeD and modified MakeBranchD.
+AliITSsimulationSDD.cxx needed a Tree indepenent way of returning back to
+the original Root Directory in function Compress1D. Now it uses gDirectory.
+
+Revision 1.64 2001/11/19 16:17:02 nilsen
+Applyed fixes to bugs found by Rene Brun. With many thanks. Some additonal
+bugs found by Rene require more work to fix. Will be fixed soon.
+
+Revision 1.63 2001/10/24 21:16:34 nilsen
+Removed some dead code and improved comments/documntation.
+
+Revision 1.62 2001/10/21 19:23:21 nilsen
+Added function to allow to limit which detectors to digitize and reconstruct.
+The default is All. This change makes no changes to any root file.
+
+Revision 1.61 2001/10/11 15:26:07 mariana
+Correct HitsToFastRecPoints
+
+Revision 1.60 2001/10/04 22:38:10 nilsen
+Changes made to support PreDigits (SDigits) plus other helpful changes.
+
+Revision 1.59 2001/08/30 09:56:18 hristov
+The operator[] is replaced by At() or AddAt() in case of TObjArray.
+
+Revision 1.58 2001/07/26 15:05:29 hristov
+Use global gRandom generator (M.Ivanov)
