24 Class
25     Foam::quadraticLinearFitPolynomial
27 Description
28     Quadratic/linear polynomial for interpolation fitting:
29         quadratic normal to the face,
30         linear in the plane of the face for consistency with 2nd-order Gauss.
32     Can be used with the CentredFit scheme to create a quadratic surface
33     interpolation scheme
