Fixes 51, which was a small regression on CLI argument parsing causing `--help` and `--version` to be broken. Thanks bollwyvl for reporting!

This is a major release solely to the fact that the CLI "API" has changed.

Other than that this brings small README fixes courtesy of ankitshubham97, thanks for the contributions Ankit!

This fixes a small issue that made our `setup.py` incompatible with Python2: 45

This release brings a couple new features:

- Function style fixing (39, 40)
- `--version` command (41)

There are also a few bug fixes contained within those PRs, and some new unit tests.

This will be the last major release before the redesign, hopefully.

Changes:

* Added a --check option
* 30 & 35
* Added unit tests
* 31 & 37
* Fixes for 29
* 36
* Fixes an issues regarding multiline strings
* 38

Thanks to f18m for all the changes and improvements!

28 Relicensed the project to MIT throughout.
