Detailed Description

Reconstructs v^{n+theta} = B^{-1}(v^n - theta dt grad_polar phi^{n+theta}) and writes mom = rho^n v^{n+theta}.

grad_polar phi is the CENTERED difference: (d_r phi, (1/r) d_theta phi). rho read from the state (Density role), FROZEN. NAMED device-clean functor. Polar counterpart of SchurReconstructKernel.
