Purpose:        Test preservation of 2nd order in  TV norme restoration.

Paper:          "Mathematical models for Local Deterministic Inpaintings.",
                        page 15 to 23 
                        Tony Chan & Jianhong Shen , Report 1999, UCLA.

Purpose:        Second order filter like the Rudin/Osher/Fatemi filter are very
            good denoiser. But is some application, to much details are destroyed.
                        Also, second order filters introduce a staircase effect in images.
                        (like linear steps). Higher order filters can better maintain 
                        non-linear information and details, this happens at the cost of
                        maintaining some noise. This is a tradeoff, your choice, or perhaps
                        we may need a kind of "linearity" indicator to decide what type of local restoration
                        should be used.
                        Compute the divergent on a 1/2,1/2 stencil from 1,1 stencil
