Fixes - Parallel errors, extension for Windows, import errors, path

[TheGreatFox]

This pull request is larger than than expected:

• Some gitignore additions
• Import errors related to: mayavi and multiprocessing
• Initial implementation of pathlib on pycommand quantum-honeycomp.py
• Rename quantum-honeycomp to quantum-honeycomp.py to allow for operation on Windows.
• Change /tmp folder to tmp folder in the root directory of the program. /tmp does not exist on Windows machines and the data stored is small.
• Minor formatting changes (pep8 standard) on py-command and quantum-honeycomp.py. Improves readability of code.
• Switch from os.system execution of python to subprocess execution (improves error checking to the function level).

The major feature is that this would allow for operation on Windows machines, once the user has already installed Anaconda with the appropriate libraries. There are still some errors with viewing 3D objects.

Tested with Windows and Ubuntu VM, but please check on Mac and your own Ubuntu VM to see if there is some unintended behavior.
