With cubic splines, there is freedom in choosing the interpolants, so
there are many different "cubic" spline interpolation schemes.

Matlab's interp1's 'cubic' mode apparently produces a C1 continuous
spline that is monotonicity-preserving. I don't think such a mode is
currently implemented in Scipy.
