As far as I can see the __init__ way of doing things creates a field
as opposed to a base_field. Given that this is done in the __init__
method every instance will have this field. Is there any disadvantage
in this? I suppose you could also have a base_field with the same name/
key. Looking at the django code there doesn't seem to be any real
difference between a base_field and a field that is created in the
__init__ method; or maybe I've missed something.
