2018 Maintance Updates

[djstein]

• update urls to paths for Django 2
• define that only Python 3 is available (depreciate Python 2, if Django foundation is getting rid of it, it's time)
• add Pipfile and Piplock for Pipenv (https://github.com/pypa/pipenv)
• update setup.py and associated files based on https://github.com/kennethreitz/setup.py
• remove parser and throttle class variables such that the user defined REST_FRAMEWORK settings are those used instead. is allows the browse-sable API to be used as well!
• update gitignore with standard Python values
• update README to use markdown over rst as new PyPi now supports it!
• remove string formating using % as it is slower than using .format()
• use absolute paths over relative paths
• general style updates

@jakeprem anything you want to weight in on?

[djstein]

I am attempting to update the .travis.yml and tox.ini files based on what is described here but need a bit of help!

[djstein]

@aaronn how do you feel about the switch to Django 2 aka Python 3 only?

[aaronn]

@djstein I'm cool with switching to Python 3 and Django 2

[djstein]

@aaronn got builds to pass on Python 3.5 and above, thoughts on removing 3.3, 3.4 from build?

[aaronn]

@djstein oops, sorry– just changed some stuff. yeah I don't mind going 3.6+ even

[djstein]

haha with my previous commit it worked without tox-travis should we use tox-travis or just standard tox? Edit: I am not familiar with tox-travis

[aaronn]

@djstein feel free to roll 9c08d8b back and take out tox-travis. thought I figured out what was causing the travis failures. I'm not really familiar with tox or travis.

[djstein]

so for the tox file: [tox] envlist = flake8-py3, py36, pypy do we also need to remove those and let the environment be decided by the travis python version

[aaronn]

@djstein not sure, you had 3.5+ working earlier right? let's just use whatever you had working there

[aaronn]

@djstein seems like it's passing fine?
