Version 0.2 suports "multi-object-recurrences" that is, single recurrences that can track the notification state of a variety of objects.
With this are a number of new methods, but most notable is the `check_due` method to localized recurrence, which takes a list of objects (which can be a heterogeneous list of `django.db.models.Model` instances) and returns only those objects who are due to be acted upon based on the given recurrence.
This release also includes the ability to update a recurrence's schedule directly from the recurrence's object. Also, as part of the "mulit-object-recurrences" interface, all update methods take an optional `for_object` method which will update the schedule of the given object, rather than the master recurrence's schedule.
