Added Sonnet_Full_Simulation.py to repo. Also moved some files into directory Obsolete/ . Draw_Mask.py now includes the code of Draw_Sensor.py and Draw_Resonator.py in a single file. This was necessary in order to put all the mask text into a single text cell which is added to mask at the same level as the sensor cell references are added.  Sonnet_Full_Simulation.py can draw a working sonnet file but still need to add code to allow it to add an internal port on the resonator.
Making this commit after about a month of not coding. Not sure what has changed since the previous commit, but changes are probably most concentrated in Sonnet_Full_Simulation.py
