Mike J. came tonight and he fixed Sensoray (elog #6645). He recompiled it and fixed it.

I made a python wrapper script for Sensoray scripts. It currently lives in /users/yuta/scripts/videocapture.py.
If you run something like
  ./videocapture.py AS
it saves image capture of AS to /users/yuta/scripts/SensorayCapture/ directory with the GPS time.
Below is the example output of AS when MI is aligned. We still see some clipping in the right. This clipping is there when one arm is mis-aligned and clipping moves together with the main beam spot. So, this might be from the incident beam, probably at the Faraday.

Currently, videocapture.py runs only on pianosa, since Sensoray 2253S is connected to pianosa. Also, it can only capture MON4. My script changes MON4 automatically.
