Detailed Description

POLAR condensed tensor coefficients A = I + c rho B^{-1} at cell centers.

Polar re-labeling of the Cartesian coefficients (#124, SchurOperatorCoeffKernel): x -> r, y -> theta. The SAME 2x2 B^{-1} (Lorentz rotation) because the force v x B is independent of the orientation of the local orthonormal frame (cf. header). NAMED device-clean functor.
