-      arguments defining options for the created FormSet constructor - all
-      arguments other than those defined below will be added to the new formset
-      constructor's ``prototype``, so this object can also be used to define new
-      methods on the resulting formset, such as a custom ``clean`` method.

-   :param Function kwargs.formset:
-      the constructor which will provide the prototype for the created FormSet
