-Revision 1.15 2003/03/21 13:58:14 masera
-Fix to avoid out-of-detector fast rec points (problem occurring for tracks entering and exiting the same side of a sensitive volume)
-
-Revision 1.14 2002/10/14 14:57:00 hristov
-Merging the VirtualMC branch to the main development branch (HEAD)
-
-Revision 1.10.4.2 2002/07/24 09:27:50 alibrary
-Updating on VirtualMC
-
-Revision 1.13 2002/06/12 18:59:47 nilsen
-Added Starting track location to hit class and related changes to modules.
-This is at present still fully backwards compatible since starting hits
-are still written to the file. When aliroot v4.0 will be released, this
-backwards compatiblity will be broken by removing the enterence hit, and making
-the nessesary changes to module at that time.
-
-Revision 1.12 2002/06/10 17:31:03 nilsen
-Replaced TArrayI expansion with Root version.
-
-Revision 1.11 2002/06/04 18:43:15 nilsen
-Fix to avoid divide by zero problem in MedianHitG and MedianHitL for track
-that enter and exit the same side of a detector sensitive volume. Needed
-for Fast simulation. Thanks to Nicola Carrer.
-
-Revision 1.10 2002/03/15 17:21:54 nilsen
-Removed zero-ing of fModules variable in constructors.
-
-Revision 1.9 2000/10/04 19:46:39 barbera
-Corrected by F. Carminati for v3.04
-
-Revision 1.8 2000/10/02 16:32:57 barbera
-Forward declarations added and formatting
-
-Revision 1.3.4.8 2000/10/02 15:55:26 barbera
-Forward declarations added and formatting
-
-Revision 1.7 2000/09/22 12:36:38 nilsen
-Minor changes to improve compilation and create less NOISE.
-
-Revision 1.6 2000/07/10 16:07:18 fca
-Release version of ITS code
-
-Revision 1.3.4.2 2000/03/02 21:42:29 nilsen
-Linked AliDetector::fDigit to AliITSmodule::fDigitsM and AliITS::fITSRecPoints
-to AliITSmodule::fRecPointsM. Renamed AliITSmodule::fPointsM to fRecPointsM.
-Removed the deletion of fDigitsM from the distructor since it is only a copy
-of what is in AliDetector. Fixed a bug in the functions LineSegmentL and
-LineSegmentG. Added two new versions of LineSegmentL and LineSegmentG to
-additionaly return track number from the hit. Removed FastPoint function,
-haven't found anywere it was used, also it had very many problems, should
-just call FastPointSPD... .
-
-Revision 1.3.4.1 2000/01/12 19:03:32 nilsen
-This is the version of the files after the merging done in December 1999.
-See the ReadMe110100.txt file for details
-
-Revision 1.3 1999/10/04 15:20:12 fca
-Correct syntax accepted by g++ but not standard for static members, remove minor warnings
-
-Revision 1.2 1999/09/29 09:24:20 fca
