Subject: MC error signal monitoring 

The other day, I hooked up the agilent analyzer to OUT2 of the MC board, which is currently set to output the MC refl error signal.  I've written a GPIB-based program that continuously polls the analyzer, and plots the live spectrum, an exponentially weighted running mean, and the first measured spectrum. 

The intended use case is to see if the FSS or MC loops are going crazy when we're locking. Sometimes the GPIB interface hangs/loses its connection, and the script needs a restart.

The script lives in scripts/MC/MCerrmon
