v2.2.1

Updated music21 requirement to 2.1.2 (for Travis).

v2.2.0

- Python 3 compatibility.
- New: hierarchical clustering and dengrogram graphical output with dendrogram.py
- Refactoring/rewrite: update make_return() method in indexer.py to greatly enhance performance when creating dataframes. Uses pandas.concat() instead of pandas.DataFrame()
- Refactoring: simplified the way several indexers and experimenters internally set their settings to make their init methods easier to read. Uses .update() instead of making piecemeal changes.
- Tests: includes 15 new tests in a test suite for the dendrogram.py file and comments out 2 tests in offset.py because they are incompatible with the new version of make_return() as they pass magic mock objects to a be concatenated by pandas.concat().
- Automated test and code coverage fix
- cleanup of dependencies/requirements (big thanks to maxalbert, https://github.com/maxalbert)
- 'scripts' directory for helpful scripts
