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.

[JaneliaAPIG]

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 fbf8107. Tested on rig.

Commit 2df4564 cleans up that fix in the code. Tested on bench, though not yet on rig. Presumed working.
