Bug? in getWaveForms.m

Hi, thanks for this useful toolbox. When I tried to get waveforms by using `getWaveForms.m` with input like gwfparams.spikeTimes = [2,3,5,7,8,9], it only returned one spike.

I check the code inside, and think it maybe better to replace line50 `curUnitnSpikes = size(curSpikeTimes,1);` with `curUnitnSpikes = numel(curSpikeTimes);` . So it will not assume the input spikeTimes is a column vector.
