* ``ChangeManipulator.original_object`` stores the instance of the
object being edited.
* We set ``new_data`` to the original object's ``__dict__``. This makes
sure the form fields contain the current values of the object.
``FormWrapper`` does not modify ``new_data`` in any way, and templates
cannot, so this is perfectly safe.
* We set ``new_data`` based upon ``flatten_data()`` from the manipulator.
``flatten_data()`` takes the data from the original object under
manipulation, and converts it into a data dictionary that can be used
to populate form elements with the existing values for the object.
* The above example uses a different template, so create and edit can be
"skinned" differently if needed, but the form chunk itself is completely
