-New SDigit version of ITS Digitizer.
-
-Revision 1.1 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 independent way of returning back to
-the original Root Directory in function Compress1D. Now it uses gDirectory.
-
-Revision 1.2 2002/03/01 E. Lopez
-Digitization changed to start from SDigits instead of Hits.
-The SDigits are reading as TClonesArray of AliITSpListItem
