Turns every attribute of the Mambu object in to a string representation.

        If the object is an iterable one, it goes down to each of its
        elements and turns its attributes too, recursively.

        The base case is when it's a MambuStruct class (this one) so it
        just 'serializes' the attr atribute. Refer to
        MambuStruct.serializeStruct pydoc.

        This is perhaps the worst way to do it, still looking for a better way.
