…an_similarity where random number generation is positively the only factor affecting output

Misc: cleanup python formatting according to PEP rules in pycharm and fix path issues demo.py

2) Use a single qubit (simulated) to generate random from -0.2 to 0.2
3) 3 millions times faster than qiskit version
4) quantum random as default for derridaean_similarity

2. Make qubit class thread safe and scalable to HPC cluster (vcs dig this)
3. Note that this code is export restricted (due to quantum) (vcs will eat this up)
4. Now even faster than before! (vss doesn't care about this unfortunately)
5. comments for clarity
