Continuous integration

[williamjameshandley]

I've updated the continuous integration and test framework, in particular

• Code is now PEP8 compliant
• I removed tests/test_lint.py in lieu of running flake8 in the travis integration. This is better because it doesn't need to run the entire test suite before checking for pep8 compliance.
• Reduced to only testing python 3.6 on linux. More can be added, but there are issues attached to matplotlib for python < 3.6

It might also be wise to block people pushing to the master branch on the repository to prevent clashes as multiple people update either the paper or the framework.

Thanks! I have never worked with travis before, I hope to understand what the things you changed do exactly at the end of the day. If, in the mean time, you know how to fix the "The command "flake8 high_dimensional_sampling tests" failed and exited with 1 during ." error in travis, help would be greatly appreciated.

Good idea. I have blocked pushing to master.
