		const ReconstructLower &	reconstruct_lower_neighbor,
		const ReconstructUpper &	reconstruct_upper_neighbor,

	)

Reconstructs the evolved variables ${\tilde{E}}^i,{\tilde{B}}^i,\tilde{\psi },\tilde{\varphi },\tilde{q}$ and the generalized electric current density ${\tilde{J}}^i$.

All results are written into vars_on_face.

This is used on DG elements to reconstruct their subcell neighbors' solution on the shared faces.
