#### I don't know whether I should try to parse this from metadata, or just find square pulses in the command waveform.
### I think finding square pulses would be simpler, but makes the assumption that pulses are square. Which is probably usually true.
### what if I check the wavegenerator widget data for the function name (pulse) and then findSquarepulses, or raise an exception if it's a different function?
