improvements to waveform plotting
Closes #375 (closed)
Changes:
- User-specifiable start and end times for time domain plot
- Allow plot to be saved as pdf
- Reduce the number of frequency bins used for long signals to reduce memory
- Throw away most of the time domain waveforms, again for memory reduction
- Fix a bug in the interval plotting
- Added axis labels
- Add the PSD
- Add some more logging outputs
