Provides an `ExclusiveBooleanField` which is a boolean (db) field where only one row in the table (or optionally, a subset of table based on value of other fields) is `True` and all the other rows are `False`.

Usage:

```python

from django.db import models

from exclusivebooleanfield.fields import ExclusiveBooleanField

class MyModel(models.Model):

    the_one = ExclusiveBooleanField()

class MyModel(models.Model):

    field_1 = ForeignKey()

    field_2 = CharField()

    the_one = ExclusiveBooleanField(on=('field_1', 'field_2'))

    # `on` is a bit like a unique constraint, value of field

    # is only exclusive for rows with same value of the on fields

class MyOtherModel(models.Model):

    field_1 = CharField()

    the_one = ExclusiveBooleanField(on='field_1')

    # if `on` is just a single field you don't have to wrap in a tuple

```

Tested on Django 1.3 thru 1.8, to run tests checkout the project and `python setup.py test`
