Forward()

void Forward	(	const Vect< real_t > &	Flux,
		Vect< real_t > &	Field
	)

Computation of the primal variable n->n+1.

Vector Flux contains elementwise fluxes issued from the Riemann problem, calculated with, as left element, getNeighborElement(1) and right element getNeighborElement(2) if getNeighborElement(2) doesn't exist, we are on a boundary and we prescribe a symmetry condition
