class to encapsulate CF info for quadratic interpolation
QuadCFStencil is a wrapper around a bunch of things that allow LevelOp to do coarse-fine interpolation on a particular face of a grid.

compute second derivative in devdir_a direction at coarse point a_ivin Uses centered finite diff approximation if ivs_standard_m.contains(a_ivin ). Otherwise, it uses the stencil from second_m Asserts that a_derivdir != direction of face

compute mixed derivative (direction is unambiguous. x and y are the two directions tangential to face) at coarse point a_ivin. \ In two dimensions, always returns 0. \ Uses centered finite diff approximation if ivs_standard_m.contains(a_ivin ). It uses the stencil from mixed_sten_m.\ Returns 0 if SpaceDim != 3
