Subject: PMC locker 

I used a script (~PSL/PMC/testAutoLocker.sh) to unlock the PMC and run autlocker ~100 times to see how robust the new autlocker is.

It failed to grab it 2 out of 137 times. During those times it just went on trying to ramp the PZT even after it had gone to a rail. Once someone resurrects Rob's 'trianglewave'  script we should be OK. Even so, I think this is good enough. Please try this out via the yellow button next time the PMC needs to be locked.

It usually takes 10-30 seconds to lock, depending upon where the fringe is compared to the upper voltage rail. Good enough.
