Investigate Pypi packaging / full installation guide

[rmbarron]

Currently, getting the package to use it is a bit cumbersome. The process relies on developers being familiar with cloning a repo, and how to add it to the pythonpath on their own. We should do a combination of:

• Package this in pypi if feasible, so that installation can be done with a pip3 install command.
• Expand on the installation instructions, so that if we are asking folks to install manually, it is a fairly straightforward process.
