+Strings compared instead of pointers
+
+Revision 1.33 2001/05/30 14:04:31 hristov
+Dynamic cast replaced (F.Carminati)
+
+Revision 1.32 2001/03/23 00:12:23 nilsen
+Set Reading of AliITSgeom data from Geant3 common blocks as the default and
+not a .det file. Removed redundent calls to BuildGeometry.
+
+Revision 1.31 2001/02/13 16:53:35 nilsen
+Fixed a but when trying to use GEANT4. Needed to replace
+if(!((TGeant3*)gMC)) with if(!(dynamic_casst<TGeant3*>(gMC)))
+because just casting gMC to be TGeant3* even when it realy is a TGeant3 pointer
+did not result in a zero value. For AliITSv5asymm and AliITSv5symm, needed
+to fix a bug in the initilizers and a bug in BuildGeometry. This is now done
+in the same way as in AliITSv5.cxx.
+
+Revision 1.30 2001/02/09 20:06:26 nilsen
+Fixed bug in distructor. Can't distroy fixxed length arrays. Thanks Peter.
+
+Revision 1.29 2001/02/09 00:05:31 nilsen
+Added fMajor/MinorVersion variables and made other changes to better make
+use of the new code changes in AliITSgeom related classes.
+
+Revision 1.28 2001/02/02 23:57:28 nilsen
+Added include file that are no londer included in AliITSgeom.h
