Curve Dimensions Cluster

I came up with a decent Curve Dimensions Cluster, just posting here for feedback and to ask for help cleaning it up and making it more robust.

It works quite well in most situations I have tried it, but I am using the path mapper to be sure i have the tree in a known order. This makes it a bit rigid on the input (can only take flattened lists of curves). Would like some help to make the tree mapping more adaptable, and help finding the situations where the component breaks down...

I have had a situation where the curve extensions freak out and multiply. I will see if i can recreate and isolate it so i can post that for specific help.

Let me know if it seems useful and how i/we could improve it.

I am pretty new to grasshopper, and enjoying it alot!
