55Added charge correlation between cathods.
56In Config_slat.C, use
57 MUON->Chamber(chamber-1).SetChargeCorrel(0.11); to set the RMS of
58 q1/q2 to 11 % (number from Alberto)
59 This is stored in AliMUONChamber fChargeCorrel member.
60 At generation time, when a tracks enters the volume,
61 AliMUONv1::StepManager calls
62 AliMUONChamber::ChargeCorrelationInit() to set the current value of
63 fCurrentCorrel which is then used at Disintegration level to scale
64 appropriately the PadHit charges.

124(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
125to allow development of slat-muon chamber simulation and reconstruction code in the MUON
126framework. The changes should have no side effects (mostly dummy arguments).
127(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
128of chambers with overlapping modules (MakePadHits, Disintegration).
