67Added charge correlation between cathods.
68In Config_slat.C, use
69 MUON->Chamber(chamber-1).SetChargeCorrel(0.11); to set the RMS of
70 q1/q2 to 11 % (number from Alberto)
71 This is stored in AliMUONChamber fChargeCorrel member.
72 At generation time, when a tracks enters the volume,
73 AliMUONv1::StepManager calls
74 AliMUONChamber::ChargeCorrelationInit() to set the current value of
75 fCurrentCorrel which is then used at Disintegration level to scale
76 appropriately the PadHit charges.
77

136(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
137to allow development of slat-muon chamber simulation and reconstruction code in the MUON
138framework. The changes should have no side effects (mostly dummy arguments).
139(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
140of chambers with overlapping modules (MakePadHits, Disintegration).
