+Clean-up of coding rule violations,
+
+Revision 1.13 2000/12/07 10:41:51 hristov
+fCorr replaced by fCorrA
+
+Revision 1.12 2000/12/06 11:55:41 morsch
+Introduce SetOffsetY(Float_t off) method as simplified simulation of pad staggering.
+fOffset is the staggering offset in y.
+
+Revision 1.11 2000/11/06 09:20:43 morsch
+AliMUON delegates part of BuildGeometry() to AliMUONSegmentation using the
+Draw() method. This avoids code and parameter replication.
+
+Revision 1.10 2000/10/18 11:42:06 morsch
+- AliMUONRawCluster contains z-position.
+- Some clean-up of useless print statements during initialisations.
+
+Revision 1.9 2000/10/18 08:41:32 morsch
+Make NextPad() and MorePads() to iterate until the end.

+Revision 1.8 2000/10/03 21:48:07 morsch
+Adopt to const declaration of some of the methods in AliSegmentation.
+
+Revision 1.7 2000/10/02 21:28:09 fca
+Removal of useless dependecies via forward declarations
+
+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
+
+Revision 1.5 2000/07/13 16:19:44 fca
+Mainly coding conventions + some small bug fixes
+
+Revision 1.4 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+AliMUONSegmentation and AliMUONHitMap have been replaced by AliSegmentation and AliHitMap in STEER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 1.3 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).
