This node creates poly curve splines from mesh edges. A selection attribute input allows only using some of the edges from the mesh. The node builds cyclic splines from branchless groups of edges where possible, but when there is a three-way intersection, the spline stops. The node also transfers all attributes from the mesh to the resulting control points. In the future we could add a way to limit that to a subset of the attributes to improve performance. The algorithm is from Animation Nodes, written by @OmarSquircleArt. I added the ability to use a selection, attribute transferring, and used different variable names, etc, but other than that the algorithm is the same.
