Revision 1.6  2000/10/18 08:41:32  morsch
Make NextPad() and MorePads() to iterate until the end.

Revision 1.5  2000/10/03 21:48:07  morsch
Adopt to const declaration of some of the methods in AliSegmentation.

Revision 1.4  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 1.3  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AliMUONSegmentation and AliMUONHitMap have been replaced by AliSegmentation and AliHitMap in STEER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 1.2  2000/06/15 07:58:48  morsch
Code from MUON-dev joined

Revision 1.1.2.1  2000/06/09 21:37:56  morsch
