Thanks for the advice all.

Ah, you leave code lying around for a while and sometimes you forget what's
active.

This I found to be necessary for any use of Reorient. If you transform from z to
z, it bombs out with singular matrix in inverse thing.  Not helpful.

I don't think this is a universal solution. I'd like it to work for any spline,
whether it's ten points widely spaced along a natural_spline curve, or one
defined with a thousand points set up via trig functions.  I had an application
where I wanted it to walk around obstacles, and so I only needed to set up ten
points that avoided the obstacles. "Next point" would disrupt that system.
