No functionality was altered to the package itself, only tests and requirements were improved. A bit.

Changes some tests and documentation.

After an initial version that returned dictionaries, version v0.2 returns named tuples. So, instead of


publication["cite"]["chicago-author-date"]


you now write


publication.cite.chicago_author_date


Notice that hyphens (-) from the original api are replaced with underscores (_).

Also, if in the original API a field begins with an underscore, this underscore is removed (e.g. `_id` becomes `id`).
