(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).
