Add tests to confirm py2 and py3 behaviors #30

Closed ryanwersal closed 5 years ago

This is a little strange since it'll mean having a separate "project" (since it needs to run under py2 etc) but it seems worth it to have it as part of our check pipeline.

Couple examples:

Why does 3to2.fix_str fix unichr? I don't recall a matching unichr -> chr in 2to3.
How does unicode behave in py2 precisely?
What about print statement unpacking as seen in #22?

This should also help us identify what 3to2 fixers are necessary since we're only supporting Python 2.7.

Test suite added under py2verify folder. A new CI check pipeline has been added so these assumptions will be exercised each push/PR.
