-Revision 1.5 2000/07/03 11:54:57 morsch
-AliMUONSegmentation and AliMUONHitMap have been replaced by AliSegmentation and AliHitMap in STEER
-The methods GetPadIxy and GetPadXxy of AliMUONSegmentation have changed name to GetPadI and GetPadC.
-
-Revision 1.4 2000/06/29 12:34:09 morsch
-AliMUONSegmentation class has been made independent of AliMUONChamber. This makes
-it usable with any other geometry class. The link to the object to which it belongs is
-established via an index. This assumes that there exists a global geometry manager
-from which the pointer to the parent object can be obtained (in our case gAlice).
-
-Revision 1.3 2000/06/28 15:16:35 morsch
-(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
-to allow development of slat-muon chamber simulation and reconstruction code in the MUON
-framework. The changes should have no side effects (mostly dummy arguments).
-(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
-of chambers with overlapping modules (MakePadHits, Disintegration).
