virtual RealGradient gradient(Real t, const Point &p) const override
Function objects can optionally provide a gradient at a point. 
 
virtual Real value(Real t, const Point &p) const override
Override this to evaluate the scalar function at point (t,x,y,z), by default this returns zero...

Function that uses spline interpolation. 
 
This class interpolates tabulated functions with cubic splines.
