This document will extract the spline coefficients and will return these 4:
1. The splined plot/interpolation
2. The 1rst derivative plot/interpolate
3. The 2nd derivative as points, that you can linterp/interpolate
4. The cumulative integration, that you can linterp/interpolate

In this demo document, we have used a function, but you can do same
from your Engineering function or from your data set providing it
is sufficiently clean/smooth.

Enjoy, cheers ... Jean
