def route(self, uri, route_args):
return uri<EOL>
Provides a hook by which additional arguments may be added to
the route.  For most limits, this should not be needed; use
the filter() method instead.  Should return the URI to
connect.

:param uri: The configured URI.  May be returned unchanged.
:param route_args: A dictionary of keyword arguments that will
                   be passed to routes.Mapper.connect().  This
                   dictionary should be modified in place.
