demonstration of the edge-quadratures over a grid

a quartic divergence free velocity field is put over an unstructured triangular grid. Is is shown, how increasing the quadrature degree improves the discrete divergence

interestingly, a cubic velocity field is already integrated with 0 divergence by degree 2 Gaussian quadrature.
