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

145(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
146to allow development of slat-muon chamber simulation and reconstruction code in the MUON
147framework. The changes should have no side effects (mostly dummy arguments).
148(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
149of chambers with overlapping modules (MakePadHits, Disintegration).
