recomputeAuxiliaryVariablesFD4_4thOrder_LoopBody()

void applications::exahype2::ccz4::internal::recomputeAuxiliaryVariablesFD4_4thOrder_LoopBody	(	double *NOALIAS	QIn,
		const ::exahype2::enumerator::AoSLexicographicEnumerator &	QInEnumerator,
		const tarch::la::Vector< DIMENSIONS, double > &	patchCentre,
		const tarch::la::Vector< DIMENSIONS, double > &	patchSize,
		int	patchIndex,
		const tarch::la::Vector< DIMENSIONS, int > &	volumeIndex,
		int	normal )

Recompute auxiliary variables.

This function calculates the auxiliary variables as gradietns of the primary variables. The graident is calculated using a 5-point stencil in 1D which has 2 neighbouring cells on each side of the central one. The computation requires us to have access to 2 halo layers on each side of a given patch.
