Detailed Description

Positivity-preserving adaptive order reconstruction. See fd::reconstruction::positivity_preserving_adaptive_order() for details. The rest mass density, electron fraction, and the pressure are kept positive. Use unlimited 5th order (degree 4 polynomial) reconstruction on the metric variables.

Only the spacetime metric is reconstructed when we and the neighboring element in the direction are doing FD. If we are doing DG and a neighboring element is doing FD, then the spacetime metric, $Φ_{i a b}$ , and $Π_{a b}$ are all reconstructed since the Riemann solver on the DG element also needs to solve for the metric variables.
