18 Revision 1.6 2000/10/18 08:41:32 morsch
19 Make NextPad() and MorePads() to iterate until the end.
21 Revision 1.5 2000/10/03 21:48:07 morsch
22 Adopt to const declaration of some of the methods in AliSegmentation.
24 Revision 1.4 2000/10/02 16:58:29 egangler
25 Cleaning of the code :
28 -> some useless includes removed or replaced by "class" statement
30 Revision 1.3 2000/07/03 11:54:57 morsch
31 AliMUONSegmentation and AliMUONHitMap have been replaced by AliSegmentation and AliHitMap in STEER
32 The methods GetPadIxy and GetPadXxy of AliMUONSegmentation have changed name to GetPadI and GetPadC.
