Updated to 0.5-SNAPSHOT. Works. Great! On a more abstract topic - I'm wondering it there's a good way to use your domain objects in Pipes instead of vertices and edges? So far I've just created a new Pipe<Vertex, T> that converts the vertices to your domain object by referring to node id.
What would be a better way?
