Work done so far on new software for downstairs cryostat. Currently in the process of replacing the old QtPlot with PyPlot in control_gui.

Notes:

sim900.py actually connects to sim900, but through old packages. sim900_pyro_server.py needs to be hooked up (through sockets).

Programs in pyplot_embed_examples include examples of a simple pyro server and embedded pyplot.
