CalcDiffWave now also calculates the minimum of the differential waveform for reset filtering purposes. Added functions to plot stacked/average diff waveforms.
Fixed a few bugs and added IMaxOverEVsE plotting function. Removed reset file stuff - no need (I hope)
Added function for calculting the difference between the recorded timestamp and the T50 value of the pulse. Given an external trigger, the timestamp will correspond to that trigger time, rather than the event time - this function should correct for this effect, giving us the event time as would have been determined if the pulse triggered by itself.
