47AliMUON delegates part of BuildGeometry() to AliMUONSegmentation using the
48Draw() method. This avoids code and parameter replication.

73AliMUONSegmentation and AliMUONHitMap have been replaced by AliSegmentation and AliHitMap in STEER
74The methods GetPadIxy and GetPadXxy of AliMUONSegmentation have changed name to GetPadI and GetPadC.
75
a30a000f 76Revision 1.3 2000/06/29 12:34:09 morsch
77AliMUONSegmentation class has been made independent of AliMUONChamber. This makes
78it usable with any other geometry class. The link to the object to which it belongs is
79established via an index. This assumes that there exists a global geometry manager
80from which the pointer to the parent object can be obtained (in our case gAlice).
