Added
- Lots of documentation, including a web-hosted version.
- Many new convenience functions, such as `Anthology.get_person()`, `Anthology.find_people()`, `Volume.get_events()`, `Person.papers()`, `Person.volumes()`.
Changed
- Showing progress bars (i.e. `verbose=True`) is now the default.
- Shorter `repr()` output for many classes, sacrificing detail for better usability in interactive settings.
- `Person` objects now require a pointer to the Anthology instance.
- Bugfix: EventIndex didn't reverse-index co-located volumes.
