+Revision 1.52 2001/05/30 06:04:58 hristov
+Changes made to be consitant with changes in TPC tracking classes (B.Nilsen)
+
+Revision 1.51 2001/05/16 14:57:15 alibrary
+New files for folders and Stack
+
+Revision 1.50 2001/05/11 09:15:21 barbera
+Corrected to make fast point creation working with PPR geometry
+
+Revision 1.49 2001/05/11 07:37:49 hristov
+Legacy lines commented
+
+Revision 1.48 2001/05/10 18:14:25 barbera
+A typo corrected
+
+Revision 1.47 2001/05/10 17:55:59 barbera
+Modified to create rec points also for PPR geometries
+
+Revision 1.46 2001/05/10 00:05:28 nilsen
+Allowed for HitsToDigits function to work with versions 5, 7, 8, and 9. This
+should probably be cleaned up to only check to make sure that fITSgeom has
+been properly defined.
+
+Revision 1.45 2001/05/01 22:35:48 nilsen
+Remove/commented a number of cout<< statements. and made change needed by
+SSD code.
+
+Revision 1.44 2001/04/26 22:44:01 nilsen
+Removed dependence on layer 5/6 in AliITS::HitsToDigits. This will be
+done properly in AliITSv???.cxx via SetDefaults.
+
+Revision 1.43 2001/04/26 13:22:52 barbera
+TMatrix and TVector elimininated to speed up the code
+
+Revision 1.42 2001/04/25 21:55:12 barbera
+Updated version to be compatible with actual verion of STEER and TPC
+
+Revision 1.41 2001/04/21 15:16:51 barbera
+Updated with the new SSD reconstruction code
+
+Revision 1.40 2001/03/17 15:07:06 mariana
+Update SDD response parameters
+
+Revision 1.39 2001/03/12 17:45:32 hristov
+Changes needed on Sun with CC 5.0
+
+Revision 1.38 2001/03/07 14:04:51 barbera
+Some vector dimensions increased to cope with full events
+
+Revision 1.37 2001/03/07 12:36:35 barbera
+A change added in the tracking part to manage delta rays
+
+Revision 1.36 2001/03/02 19:44:11 barbera
+ modified to taking into account new version tracking v1
+
