knot_recursion_twistier_a

I just increased the twist on the green and magenta iterations, although I had to short circuit hoopsnake to make it work. There must be a fair bit of overhead associated with the hoopsnake because when I tried stepping through the 3rd iteration ran for hours and then ran out of memory with Rhino using about 15gig or so. I ended up baking the 2nd iteration output curve and feeding it in as a 1st iteration in order for it to work. I think I'm done with these 'torus knots' for now.
