Functions
template<class TEdgeIter >
bool	ug::CreatePolyChain (std::vector< Vertex * > &polyChainOut, Grid &grid, TEdgeIter edgesBegin, TEdgeIter edgesEnd)
	given a list of edges, this method collects associated vertices in a polychain
template<class TEdgeIterator >
std::pair< Vertex *, Edge * >	ug::GetFirstSectionOfPolyChain (Grid &grid, TEdgeIterator edgesBegin, TEdgeIterator edgesEnd, Grid::edge_traits::callback cbEdgeIsInPolyChain)
	Returns the start-vertex and start-edge of a polygonal chain.
std::pair< Vertex *, Edge * >	ug::GetNextSectionOfPolyChain (Grid &grid, std::pair< Vertex *, Edge * > lastSection, Grid::edge_traits::callback cbEdgeIsInPolyChain)
	returns the next section in a polygonal chain.
template<class TEdgeIterator >
size_t	ug::GetPolyChainType (Grid &grid, TEdgeIterator edgesBegin, TEdgeIterator edgesEnd, Grid::edge_traits::callback cbEdgeIsInPolyChain)
	returns an or combination of constants enumerated in PolyChainTypes.
bool	ug::SplitIrregularPolyChain (SubsetHandler &sh, int srcIndex, int targetIndex)
	Makes sure that the polychain at srcIndex is regular and not separated.
