- change tests to use vcrpy so they are more reliable
- add
original_exception
toeasypost.Error
in cases where we are re-raising an underlying error (e.g., an HTTP exception) - fix a bunch of flake8 warnings
- [potentially-breaking] soft-deprecate Python 3.3 and 3.4. these have been dropped by most of the libraries we use, so probably don't work anyway.
- Swap GET to POST on Refund method
