2ae08086 17Revision 1.5 2000/10/02 16:58:29 egangler
18Cleaning of the code :
19-> coding conventions
20-> void Streamers
21-> some useless includes removed or replaced by "class" statement
22
ecfa008b 23Revision 1.4 2000/07/03 11:54:57 morsch
24AliMUONSegmentation and AliMUONHitMap have been replaced by AliSegmentation and AliHitMap in STEER
25The methods GetPadIxy and GetPadXxy of AliMUONSegmentation have changed name to GetPadI and GetPadC.
