Grouping intersecting curves/ network of curves

So far I found 3 methods that have been done before none of them that I could make work due to specific lack of knowledge in each method. 

1. Couldn't work out what the expressions were in the method, but non the less this is a good visualisation of what I am looking for.2. A C# method of the above example http://pastebin.com/VRUtS64x sad to admit that I have never used C# component before to understand how to make it work in grasshopper. Here is the post it came from. http://www.grasshopper3d.com/forum/topics/how-to-distribute-serval-...

3. This old polyclustering method that I found, not sure if I am doing something wrong or it's just outdated but I have attached the method file bellow with lines internalised.
