Data Fields
inType (	QIn )[2 *DIMENSIONS]
	QIn may not be const, as some kernels delete it straightaway once the input data has been handled.

	Id of underlying task.
const int	numberOfCells
	As we store data as SoA, we have to know how big the actual arrays are.
const tarch::MemoryLocation	memoryLocation
	We might want to allocate data on the heap or an accelerator, therefore we save the target device id.

	We might want to allocate data on an accelerator, therefore we save the target device id.

	Out values.

Detailed Description

template<typename inType = double, typename outType = double>
struct exahype2::CellFaceData< inType, outType >

Represents the faces of one cell, with a total of 2*Dim faces per cell For ADER QIn will contain the values, QOut would contain the fluxes The faces can still each be made to contain either only the values for the given cell, or those and the neighbours' values.

template<typename inType, typename outType>

exahype2::CellFaceData< inType, outType >::CellFaceData	(	inType *	QIn_[2 *DIMENSIONS],

Construct patch data object for one single cell.

Usually, I do so only to be able to use the same kernels everywhere: Kernels accept CellFaceData, i.e. multiple patches. Even if we have only one cell, we thus wrap this cell's data into an instance of CellFaceData and pass it in. The id can be set to any dummy in this case, as we know which task has wrapped this single cell, i.e. we usually do not read it later.
