19Cleaning of the code (continued ) :
20-> coding conventions
21-> void Streamers
22-> some useless includes removed or replaced by "class" statement

8c449e83 24Revision 1.5 2000/06/28 15:16:35 morsch
25(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
26to allow development of slat-muon chamber simulation and reconstruction code in the MUON
27framework. The changes should have no side effects (mostly dummy arguments).
28(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
29of chambers with overlapping modules (MakePadHits, Disintegration).
