Functions
void	peano4::grid::clear (GridStatistics &statistics, bool isGlobalMasterTree)
	The term clear() is not 100% correct, as the number of stationary traversals is not reset to a dummy but instead incremented.
std::vector< GridControlEvent >	peano4::grid::merge (std::vector< GridControlEvent > events, const double Tolerance=0.1)
	Merge set of refinement/coarsening commands.
GridVertex	peano4::grid::createVertex (GridVertex::State state, const tarch::la::Vector< Dimensions, double > &x, int level, const tarch::la::Vector< TwoPowerD, int > &adjacentRanks, bool isNewFineGridVertex)
	Factory mechanism.
bool	peano4::grid::isSpacetreeNodeRefined (GridVertex vertices[TwoPowerD])
	A spacetree node is refined if any of its adjacent vertices holds one of the following flags:
bool	peano4::grid::willVertexBeRefined (const GridVertex &vertex)
	A vertex will be refined if it is already refined or currently refining.
bool	peano4::grid::hasVertexBeenRefined (const GridVertex &vertex)
	A vertex has been refined if it is (already) refined or is erasing or the erase has been triggered.
std::bitset< TwoPowerD >	peano4::grid::willVerticesBeRefined (GridVertex vertices[TwoPowerD])
	A vertex is unrefined if it is hanging.
std::bitset< TwoPowerD >	peano4::grid::haveVerticesBeenRefined (GridVertex vertices[TwoPowerD])
bool	peano4::grid::isSpacetreeNodeLocal (GridVertex vertices[TwoPowerD], bool splittingIsConsideredLocal, bool joiningIsConsideredLocal, int id)
	A spacetree node as 2^d adjacent vertices.
std::string	peano4::grid::toString (VertexType type)
std::string	peano4::grid::toString (FaceType type)
std::string	peano4::grid::toString (CellType type)
constexpr int	peano4::grid::InvalidRank (-1)
std::string	peano4::grid::toString (SpacetreeState state)
bool	peano4::grid::overlaps (const tarch::la::Vector< Dimensions, double > &x, const GridControlEvent &event)
bool	peano4::grid::overlaps (const AutomatonState &x, const GridControlEvent &event)
bool	peano4::grid::isContained (const AutomatonState &x, const GridControlEvent &event, double upscaleAutomatonState=1.0)
	isContained() is defined over the closed interval, i.e.
void	peano4::grid::reduceGridControlEvents (std::vector< GridControlEvent > &events)
	Peano 4 does not reduce any grid control events globally.
std::string	peano4::grid::toString (const std::vector< GridControlEvent > &events)
std::string	peano4::grid::toString (const std::list< GridControlEvent > &events)
void	peano4::grid::internal::removeEraseEventsThatAreCancelledByRefineEvents (const std::list< peano4::grid::GridControlEvent > &refineEvents, std::list< peano4::grid::GridControlEvent > &eraseEvents)
	This is the first thing I do.
void	peano4::grid::internal::mergeAdjacentRefinementEvents (std::list< peano4::grid::GridControlEvent > &inputEvents, int Tolerance)
	Merge adjacent events.
bool	peano4::grid::internal::twoEventsOverlap (const peano4::grid::GridControlEvent &lhs, const peano4::grid::GridControlEvent &rhs)
	Helper function which helps us throughout the merge.
bool	peano4::grid::internal::equals (const peano4::grid::GridControlEvent &lhs, const peano4::grid::GridControlEvent &rhs)
bool	peano4::grid::internal::refinementEventOverrulesCoarsening (const peano4::grid::GridControlEvent &refineEvent, const peano4::grid::GridControlEvent &eraseEvent)
	A refinement event overrules the coarsening if.
bool	peano4::grid::internal::twoEventsAreAdjacent (const peano4::grid::GridControlEvent &lhs, const peano4::grid::GridControlEvent &rhs, double Tolerance)
	Are two events adjacent.
void	peano4::grid::internal::sort (std::list< peano4::grid::GridControlEvent > &events)
	Sort grid control events geometrically.
