Stimulus triggered waveform display (Hantman Lab)

sync signal, clarify mode - is it similar to, or the same as gate mode? Or is gate mode a precondition for implementation?

Austin Graves in Hantman lab requests this feature. It's a hybrid of the classic Waveform & Raster display modes. It's Waveform display mode, but with the selective display based on a (common) stimulus channel, rather than spike detection at each channel.

Since Raster mode already implements stimulus triggering, user implementation would use the same stimulus channel property that's specified for Raster mode.

If stimulus is never detected, there will never be anything displayed. Only display the signal whenever the stimulus is detected.

[JaneliaAPIG]

This feature is basically no longer spike detection.

needs bench testing; also need to check to see if raster mode is still working after all the changes

• Rig tested
• Raster mode restored

Future issues discovered during work on this issue:

• Issue 53 ** This limits the max stimulus rate for a given timer period

• Issue 55 ** This can cause some stimuli to be missed, in rare cases. For r1.0, Spoke does not guarantee all stimuli are processed.

• Issue 56

• Issue 57

Rig demo uncovered a sporadic issue with stim-triggered waveform. Fixed as of fbf8107f17ec2418613c543e2f8ef63051ef3f1e. Tested on rig.

Commit 2df4564daafdb7cfc4faca1b427751f4bbb5aaed cleans up that fix in the code. Tested on bench, though not yet on rig. Presumed working.
