        ## Installation
        
        Download the source from https://pypi.python.org/pypi/django-eventtools/
        and run `python setup.py install`, or:
        
            > pip install django-eventtools
        
        Django 1.8 or higher is required.
        
        
        ## Setup
        
        Given the following models:
        
            from django.db import models
        
            from eventtools.models import BaseEvent, BaseOccurrence
        
        
            class Event(BaseEvent):
                title = models.CharField(max_length=100)
        
        
            class Occurrence(BaseOccurrence):
                event = models.ForeignKey(Event)
        
        
        ## Usage
        
        Create a sample event & occurrences
        
            >>> from datetime import datetime
            >>> from dateutil import rrule
            >>> from myapp.models import Event
            >>> event = Event.objects.create(title='Test event')
            >>> once_off = Occurrence.objects.create(
                    event=event,
                    start=datetime(2016, 1, 1, 12, 0),
                    end=datetime(2016, 1, 1, 2, 0))
            >>> christmas = Occurrence.objects.create(
                    event=event,
                    start=datetime(2015, 12, 25, 7, 0),
                    end=datetime(2015, 12, 25, 22, 0),
                    repeat=rrule.YEARLY)
            >>> daily = Occurrence.objects.create(
                    event=event,
                    start=datetime(2016, 1, 1, 7, 0),
                    end=datetime(2016, 1, 1, 8, 0),
                    repeat=rrule.DAILY)
        
        `Event` and `Occurrence` instances, and their associated querysets, all support
        the `all_occurrences` method, which takes two optional arguments - `from_date`
        and `to_date`, which may be dates or datetimes. `from_date` defaults to the
        current day, `to_date` to `None`. The method returns a python generator
        yielding tuples in the format `(start, end, data)` - for example:
        
            >>> Event.objects.all().all_occurrences()
            >>> event.all_occurrences(from_date=datetime(2015, 1, 1, 10, 0))
            >>> event.occurrence_set.all().all_occurrences(to_date=date(2016, 1, 1))
            >>> occurrence.all_occurrences(from_date=date(2016, 1, 1),
                                           to_date=date(2016, 12, 31))
        
        A `next_occurrence` method is also provided, taking the same arguments,
        but returning a single occurrence tuple.
        
            >>> event.next_occurrence()
            >>> event.next_occurrence(from_date=date(2016, 1, 1))
        
        
        ### Queryset filtering
        
        Querysets can also be filtered, but due to uncertainty with repetitions,
        from_date filtering is only an approximation (to_date filtering is accurate).
        If you need a queryset filtered exactly, pass `exact=True` - this will filter
        using occurrences but still return a queryset - but be careful with this as it
        may be very slow. For example
        
            >>> Event.objects.for_period(from_date=date(2015, 1, 1),
                                         to_date=date(2015, 12, 31))
            >>> event.occurrence_set.for_period(from_date=date(2015, 1, 1), exact=True)
        
        
        ### Adding additional data to occurrence tuples
        
        If you need more information about the occurrence than just a pair of dates,
        add an occurrence_data property to your `BaseOccurrence` subclass - i.e.
        
            class Occurrence(BaseOccurrence):
                event = models.ForeignKey(Event)
        
                @property
                def occurrence_data(self):
                    return {
                        'event_title': self.event.title,
                        'image': self.event.image,
                    }
        
        The result will be appended to the occurrence tuple, i.e. `(start, end, data)`
        
        
        ## Running tests
        
        Assuming virtualenvwrapper is installed:
        
            > cd path-to/django-eventtools
            > mkvirtualenv test
            > ./setup.py install
            > ./runtests.py
        
        
        ## Todo
        
        ✔ Handle from_date more efficiently in BaseOccurrence.all_occurrences
        - Test for_period methods with exact=False
        - Python 3 tests (tox)
