-Revision 1.12 2000/06/12 23:43:16 nilsen
-New ITS code replacing the old structure and simulations code.
+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.

-fixed posible compilation errors on HP unix
+Revision 1.64 2001/11/19 16:17:02 nilsen
