ERRANT v2.0.0

See CHANGELOG.md for previous updates.

v2.0.0 (10-12-19)

1. ERRANT has been significantly refactored to accommodate a new API (see README). It should now also be much easier to extend to other languages.

2. Added a setup.py script to make ERRANT pip installable.

3. The Damerau-Levenshtein alignment code has been rewritten in a much cleaner Python implementation. This also makes ERRANT ~20% faster.

Note: All these changes do not affect system output compared with the previous version. For the first pip release, we wanted to make sure v2.0.0 was fully compatible with the BEA-2019 shared task on Grammatical Error Correction.

Thanks to @sai-prasanna for inspiring some of these changes!
