-Revision 1.6 2000/10/02 16:58:29 egangler
-Cleaning of the code :
--> coding conventions
--> void Streamers
--> some useless includes removed or replaced by "class" statement
+/* $Id$ */
-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-AliMUONSegmentation and AliMUONHitMap have been replaced by AliSegmentation and AliHitMap in STEER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).
