Kevin, Sheila, help from TJ and others

I started a script running on my nomachine session that should start a 10kHz ADF sweep at 11, step down the CO2s at around 12:30, measure nlg and rerun the ADF sweep at 1:30 and again at 3am.  If the IFO stays locked through all this the CO2s will be set back to normal at 4:30 am.  If the IFO unlocks the script will quit and the CO2s will be reset by the guardians.
