0007  *
0008  * Cross-talk generator for digitization simulation of Endcap Muon CSCs.
0009  * We model crosstalk by making the signal on a neighboring
0010  *    strip or wire proportional to the slope of the original
0011  *    signal.  The constant should be chosen to give the appropriate
0012  *    level of crosstalk, maybe 10% of the signal. The user is responsible
0013  *    for subtracting the crosstalk from the input signal,
0014  *    and adding the crosstalk signal to the neighbors.
