Functions
template<typename FaceLabel >
double	exahype2::internal::getMinTimeStampOfNeighbours (const peano4::datamanagement::FaceEnumerator< FaceLabel > &faceLabelEnumerator)
	Run over all neighbours and analyse their time stamp.
template<typename CellLabel , typename FaceLabel >
double	exahype2::getMinTimeStampOfNeighboursAhead (const CellLabel &cellLabel, const peano4::datamanagement::FaceEnumerator< FaceLabel > &faceLabelEnumerator)
	Similar to getMinTimeStampOfNeighbours(), but we minimise only over those neighbours that are actually ahead.
template<typename CellLabel , typename FaceLabel >
bool	exahype2::runTimeStepOnCell (const CellLabel &cellLabel, const peano4::datamanagement::FaceEnumerator< FaceLabel > &faceLabelEnumerator, double globalMinTimeStamp)
	Determine whether to run a time step on a cell by analysing the neighbouring cells' timestamp.
template<typename CellLabel , typename FaceLabel >
double	exahype2::removeTimeStepAccumulationErrorsFromCell (const CellLabel &cellLabel, const peano4::datamanagement::FaceEnumerator< FaceLabel > &faceLabelEnumerator, double timeStepSize)
	Remove accumulation errors from cell time stamps.
std::pair< double, double >	exahype2::getInterpolationWeights (double oldTimeStampOnFace, double newTimeStampOnFace, double cellTimeStamp)
double	exahype2::discretiseAndTruncateTimeStepSizes (double cellTimeStepSize, double maxGlobalTimeStepSize, int discretisationStepsSize)
	Discretise (bucket) time step sizes and truncate it.
