Hi Welson,
It seems LabeledElement never really got implemented, so for now its
presence is just confusing.
If you want to add a label to an edge, all you need to do is write your
own edge class (probably subclassing one of the existing ones such as
DirectedEdge) and add whatever attributes you want there. And supply a
corresponding edge factory to your graph.
