Unroll Command

From what I understand, there isn't a way to use the Rhino Unroll command in Grasshopper, correct? 

I'll searched around and found a few definitions that try to duplicate it, but they aren't completely accurate to what the Unroll command does.  I basically need to unroll a bunch of geometry and manually it is doable, but will be time consuming. It would be great if that command was accessible from grasshopper!  

Anyone have any direction on the best way to do this in Grasshopper?

Cheers,

Matt
