def lookupProcedure(self, procedurePath):
        """
        Given a string naming a procedure, return a callable object for that
        procedure or raise NoSuchFunction.

        The returned object will be called, and should return the result of the
        procedure, a Deferred, or a Fault instance.

        Override in subclasses if you want your own policy.  The base
        implementation that given C{'foo'}, C{self.xmlrpc_foo} will be returned.
        If C{procedurePath} contains C{self.separator}, the sub-handler for the
        initial prefix is used to search for the remaining path.

        If you override C{lookupProcedure}, you may also want to override
        C{listProcedures} to accurately report the procedures supported by your
        resource, so that clients using the I{system.listMethods} procedure
        receive accurate results.
