        A function that allows a module to get re-bound to a real user if it was previously bound to an AnonymousUser.

        Will only work within a module bound to an AnonymousUser, e.g. one that's instantiated by the noauth_handler.

        Arguments:
            module (any xblock type):  the module to rebind
            real_user (django.contrib.auth.models.User):  the user to bind to

            nothing (but the side effect is that module is re-bound to real_user)
