In the example you refer too, meshes were store individually without any
specify information about the connectivity. The different model were
simply meshed together so that the interface is common.

One solution is to enrich you structure so that each halfedge might
have a corresponding halfedge in another mesh. In case you have more
than two meshes sharing an edge, you'll need to short them out.
