Assigns every node in the input network to a layer.
            The layering satisfies the following:
            if L is a link from node U to node V,
            then U.layer > V.layer;
            further, U.layer - V.layer >= LinkMinLength(L).
            This method can be overridden to customize how nodes are assigned layers.
