Making mesh/surface out of section curves

Hello. Brand new user of Grasshopper here. :)

I have written a simple algorythm generating sections of metaball blobs. It is necessary for me to use my shape control system, so I can't really use metaball blobs from other sources... I have a big problem generating a mesh/surface from those section curves:
I can have any number of sections in any plane. One would think, that such detailed net should be easy for a computer to interpret, but somehow I can't force any program I have to do it... Tried using many tools (3DSMax, Sketchup, Rhino Patching, Grasshopper commands...). Also tried using the "Cocoon" thing, but honestly I have no idea how even inputs work in this plugin (I've read the official description and still couldn't force it to work). "Exoskeleton" plugin for some reason doesn't install properly in my GH version. 

Can anyone help me? GH file attached to the message
