Line graph with attributes

[vymao]

If we have some graph with edge attributes, is it possible to generate the line graph somehow with the original edge attributes embedded into the line graph nodes? Would save a lot of hassle.

It looks like one additional line of code will transfer all the edge attributes of the original graph to the line graph as node attributes.

G = nx.path_graph(4)
G.add_edges_from((u, v, {'krill': u+v}) for u, v in G.edges)
H = nx.line_graph(G)
H.add_nodes_from((node, G.edges[node]) for node in H)

I think @dschult 's comment very nicely answers the question and IMO would be a nice addition to the docstring examples.
