Nick Smith (@LHO) tested the ditherServo.pl at Hanford.
He added options to specify exit conditions to the script. Now you can make the script exit when
a condition, such as ArmPower > 1.0, is satisfied, or let it wait until a certain condition is satisfied.
I also modified the script to use ezcastep instead of tdswrite for feedback actuation.
The script now runs ezcastep in the background while the next iteration of the tdsdmd is performed.
Instead of kicking mirrors with a big thrust each time by a single tdswrite command, ezcastep gently moves the mirrors with fine steps.
I also implemented this "background ezcastep" technique in Tobin's tdscntr.pl.
The alignment scripts run smoother now.
