I made some changed to the pylint configuration. I looked through the original lint failure in Eli's PR and in my opinion the only issue was the import errors, which I fixed by adding

pip install -r requirements.txt
pip install -e .

Then, I added (( code & 35 )) && exit 1 || exit 0 so the lint will only fail on fatal messages, error messages, and pylint failures. So any pylint warning, refactor, or convention flags won't cause the lint to fail. This is configurable by changing the number the exit code gets ANDed with.
