Evaluating Points on Curve where Curvature Circle Changes Side

Hi Marcus,

Would something like* this work. Where the angle flips from Pi to 0 at the inflection point. You would have to iterate over the length and the points would be where the greatest angle difference occurs between steps.

* I say like because this only works on a 2D curve but you could develop the idea a bit more for 3D.

does the CurveDiscontinuity component do this when you set it to curvature?

Can't check at the moment...
