Revision 1.12  2001/08/24 21:06:37  nilsen
Added more documentation, fixed up some coding violations, and some
forward declorations.

Revision 1.11  2001/05/16 08:17:49  hristov
Bug fixed in the StepManager to account for the difference in the geometry tree for the ITS pixels. This fixes both the funny distribution of pixel coordinates and the missing hits/digits/points in many sectors of the ITS pixel barrel. Also included is a patch to properly get and use the detector dimensions through out the ITS code. (B.Nilsen)

Revision 1.10  2001/02/09 00:00:57  nilsen
Fixed compatibility problem with HP unix {ios::fmtflags -> Int_t}. Fixed
bugs in iostream based streamers used to read and write .det files. Fixed
some detector sizes. Fixed bugs in some default-special constructors.

Revision 1.9  2001/02/03 00:00:30  nilsen
New version of AliITSgeom and related files. Now uses automatic streamers,
set up for new formatted .det file which includes detector information.
Additional smaller modifications are still to come.

Revision 1.8  2000/10/02 16:32:43  barbera
Forward declaration added

Revision 1.2.4.8  2000/10/02 15:53:49  barbera
Forward declaration added

Revision 1.7  2000/07/10 16:07:18  fca
Release version of ITS code

Revision 1.2.4.2  2000/03/04 23:55:59  nilsen
Fixed up the comments/documentation

Revision 1.2.4.1  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
