CP1 Overfill Via Script

I ran the script with the following settings: CP1_Fill.py 100 -130 600.  Overfill verified via one of the site cameras.

Note from script:

CP1 Fill completed in 37 seconds. Starting CP1 fill. LLCV enabled. LLCV set to manual control. LLCV set to 100% open. Fill completed in 37 seconds. TC A did not register fill. LLCV set back to 34.6% open.

From the note it appears as if TC A had some lag regarding the temperature readout, because on the attached plot it shows its temperature did go below -130 deg C.
