18 Revision 1.4 2000/10/02 16:58:29 egangler
19 Cleaning of the code :
22 -> some useless includes removed or replaced by "class" statement
24 Revision 1.3 2000/07/03 11:54:57 morsch
25 AliMUONSegmentation and AliMUONHitMap have been replaced by AliSegmentation and AliHitMap in STEER
26 The methods GetPadIxy and GetPadXxy of AliMUONSegmentation have changed name to GetPadI and GetPadC.
