Detailed Description

Cross-talk generator for digitization simulation of Endcap Muon CSCs. We model crosstalk by making the signal on a neighboring strip or wire proportional to the slope of the original signal. The constant should be chosen to give the appropriate level of crosstalk, maybe 10% of the signal. The user is responsible for subtracting the crosstalk from the input signal, and adding the crosstalk signal to the neighbors.
