-Revision 1.9 2000/10/06 15:37:22 morsch
-Problems with variable redefinition in for-loop solved.
-Variable names starting with u-case letters changed to l-case.
-
-Revision 1.8 2000/10/06 09:06:31 morsch
-Include Slat chambers (stations 3-5) into geometry (A. de Falco)
-
-Revision 1.7 2000/10/02 21:28:09 fca
-Removal of useless dependecies via forward declarations
-
-Revision 1.6 2000/10/02 17:20:45 egangler
-Cleaning of the code (continued ) :
--> coding conventions
--> void Streamers
--> some useless includes removed or replaced by "class" statement
-
-Revision 1.5 2000/06/28 15:16:35 morsch
-(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
-to allow development of slat-muon chamber simulation and reconstruction code in the MUON
-framework. The changes should have no side effects (mostly dummy arguments).
-(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
-of chambers with overlapping modules (MakePadHits, Disintegration).
-
-Revision 1.4 2000/06/26 14:02:38 morsch
-Add class AliMUONConstants with MUON specific constants using static memeber data and access methods.
-
-Revision 1.3 2000/06/22 14:10:05 morsch
-HP scope problems corrected (PH)
-
-Revision 1.2 2000/06/15 07:58:49 morsch
-Code from MUON-dev joined
-
-Revision 1.1.2.14 2000/06/14 14:37:25 morsch
-Initialization of TriggerCircuit added (PC)
-
-Revision 1.1.2.13 2000/06/09 21:55:47 morsch
-Most coding rule violations corrected.
-
-Revision 1.1.2.12 2000/05/05 11:34:29 morsch
-Log inside comments.
-
-Revision 1.1.2.11 2000/05/05 10:06:48 morsch
-Coding Rule violations regarding trigger section corrected (CP)
-Log messages included.
