Add a test for the constrained cubic interpolation of Evoral::Curve

Browse source 
Add a test, based on the worked example in www.korf.co.uk/spline.pdf, for
the constrained cubic spline interpolation.

The delta values for the float comparisons are rather arbitrary, I'm sorry
to say: they're basically chosen so that everything passes.
