v0.2.0

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).
