Copied the old hittite software from last summer to the directory.
Wrote lockin_controller, which currently has methods to send and receive data from the lockin.
Added stub methods.
Spent a long time investigating weird behavior... and found that we needed a small delay. We don't really understand why, but now it works.
Created hittite controller, which works well. Also created the sweep_script, which should sweep a specified range and take data. However, the issues we observed with the rs 232 connection are back: only starred commands can be sent and received. Going to try a different cable.
