clean_data will include a key and value for *all* fields defined in the Form,
even if the Form's data didn't include a value for fields that are not
required. In this example, the data dictionary doesn't include a value for the
"nick_name" field, but clean_data includes it. For CharFields, it's set to the
empty string.
>>> class OptionalPersonForm(Form):
... first_name = CharField()
... last_name = CharField()
... nick_name = CharField(required=False)
>>> data = {'first_name': u'John', 'last_name': u'Lennon'}
>>> f = OptionalPersonForm(data)
>>> f.is_valid()
True
>>> f.clean_data
{'nick_name': u'', 'first_name': u'John', 'last_name': u'Lennon'}
For DateFields, it's set to None.
>>> class OptionalPersonForm(Form):
... first_name = CharField()
... last_name = CharField()

"auto_id" tells the Form to add an "id" attribute to each form element.
If it's a string that contains '%s', Django will use that as a format string
into which the field's name will be inserted. It will also put a <label> around
