Merging/branching curves cleanup

Hey fellow grasshoppers. I'm looking for a way to bundle merging curves. The problem is that I can't figure out a way of cleaning the lines I get from (principal lines from  karamba/millipede). The places where they come close to each other have to become a single line which branches. I don't expect you to do it for me , I' m asking for suggestions. I tried several ways including topologizer (http://www.grasshopper3d.com/profiles/blogs/topologizer-network-cle...) and Daniel's script (http://www.grasshopper3d.com/forum/topics/romoving-duplicate-polyli...) for duplicate polyline (assuming that if i crack up the tolerance i will get rid of the very similar curves and figure out the branching later)


Thanks!
