an include file for interpolating curves and spline. 20 different ones for 
now. It is based on work by Mr. Noskowicz. There are more in his document 
but I had trouble with gtting some to go, especialy the morph between two 
curves types.

Have a poke at it,

Ingo

After unconfusing myself I rewrote the spline framework and simplified it 
quite a bit. So, new version to poke at.

(as an excersize I also did a version of it in Nim ( https://nim-lang.org/ 
), if one is interested)

attached an updated version, fixed TCB spline, refactoring and added a CIt 
curve that takes two curves. One to modify the t value for the other 
curve. This to somewhat mimick the cuuren spline implementation in POV-Ray
