+Revision 1.38  2001/11/28 01:35:47  nilsen
+Using standard constructors instead of default constructors for Clusterfinder,
+Response, and FastSimulator.
+
+Revision 1.37  2001/10/22 11:00:54  hristov
+New naming schema of the rotation matrices in BuildGeometry() to avoid redefinition in other detectors (R.Barbera)
+
+Revision 1.36  2001/10/19 21:32:35  nilsen
+Minor changes to remove compliation warning on gcc 2.92.2 compiler, and
+cleanded up a little bit of code.
+
+Revision 1.35  2001/10/19 10:16:28  barbera
+A bug corrected in the definition of a TPCON
+
+Revision 1.34  2001/10/18 12:25:07  barbera
+Detailed geometry in BuildGeometry() commented out (450 MB needed to compile the file). Six cylinders put back but improved by comparison with the ITS coarse geometry
+
+Revision 1.33  2001/10/18 03:09:21  barbera
+The method BuildGeometry() has been completely rewritten. Now display.C can display the detailed ITS geometry instead of the old six dummy cylunders.
+
+Revision 1.32  2001/10/17 04:35:32  barbera
+Checks for the det and chip thickness modified in order to set the dafault values to 200 um if the user chosen values are outside the range 100-300 um
+
+Revision 1.31  2001/10/04 22:33:39  nilsen
+Fixed bugs in SetDefaults.
+
+Revision 1.30  2001/10/01 19:34:09  nilsen
+Fixed a bug in asigning detector types in SetDefaults under SSD layer 6.
+
+Revision 1.29  2001/06/07 14:42:14  barbera
+Both chip and det thicknesses set to [100,300]
+
+Revision 1.28  2001/05/31 19:24:47  barbera
+Default values of SPD detector and chip thickness set to 200 microns as defined by the Technical Board
+
+Revision 1.27  2001/05/30 16:15:47  fca
+Correct comparison wiht AliGeant3::Class() introduced. Thanks to I.Hrivnacova
+
+Revision 1.26  2001/05/30 15:55:35  hristov
+Strings compared instead of pointers

+Overlaps corrected. (R. Barbera)
+
+Revision 1.22  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 1.21  2001/05/10 00:12:59  nilsen
+Finished fixing up the default segmentation for the PPR geometry.
+
+Revision 1.20  2001/05/09 01:02:22  nilsen
+Finished fixing SetDefaults for the segmentation of SPD, SDD, and SSD.
+
+Revision 1.19  2001/05/03 08:40:15  barbera
+Volume ITSD slightly modified to be consistent with v5. Some improvement in the printouts. The last commit did not complete successfully.
+
+Revision 1.17  2001/05/01 22:40:42  nilsen
+Partical update of SetDefault.
+
+Revision 1.16  2001/04/22 13:48:09  barbera
+New values of media parameters and thickness of SPD end-ladder electronics as given by Fabio Formenti
+
+Revision 1.15  2001/04/04 07:02:16  barbera
+Position of the cylinders holding rails corrected
+
+Revision 1.14  2001/03/29 22:02:30  barbera
+Some changes to the services due to the new drawings from the engineers.
+
+Revision 1.13  2001/03/29 05:28:56  barbera
+Rails material changed from aluminum to carbon fiber according with the decision of the last Technical Board
+
 Revision 1.12  2001/03/28 06:40:20  barbera
 Central and services mother volumes made consistenf for detailed and coarse geometry. Switch for rails added to the coarse geometries
