-----
* Added experimental Python 3 support.
* Added extensive test coverage (from 0% to 81%).
* Added documentation (including this changelog).
* Removed ``RecurrenceModelField`` and ``RecurrenceModelDescriptor``,
which don't appear to have worked as expected for some time.
* Fixed a bug introduced in 1.0.3 which prevented the
django-recurrence JavaScript from working 27.
* Don't raise ``ValueError`` if you save ``None`` into a
``RecurrenceField`` with ``null=False`` 22, for
consistency with other field types.
* Make sure an empty recurrence object is falsey 25.
* Fix a copy-paste error in ``to_recurrence_object`` which prevented
exclusion rules from being populated correctly.
* Fix a typo in ``create_from_recurrence_object`` which prevented it
working with inclusion or exclusion rules.
* Various other very minor bugfixes.
