Displaying Nurbs Curve Knots in GH? Knot Vectors?

Hi Folks,

For students, I'd like to display Nurbs Curve Knots in GH -- similar to Rutten's excellent diagram in "Rhinoscript 101" (see attached).  C'est possible?

If so, I could use some insight on how to do this. I'm guessing Knot Vectors might be a good start, but I'm a little unsure how this module works.

Enclosed are the beginnings of GH and Rhino5 files, based on Payne & Issa's Curve Types example in their Grasshopper Primer.  Questions are listed in the GH file.

Feel free to tweak the GH file -- any insights are much appreciated!
