- Revision 1.9.8.4  2003/06/13 16:31:00  nilsen
- Introducing a backward incompatibility to hit files created before June 12
- 2002. The enterance hit is no longer recorded. The starting position of
- every hit is used instead. Added GetPositionL0 to AliITShit, fixed up
- AliITSmodule to use starting location of hit and not enterance hits, and
- StepManager in AliITSvPPRasymm no longer records enterence hit to hit file.
