Functions
template<typename InternalType1 , typename InternalType2 , typename InternalType3 >
void	amg_coarse (unsigned int level, InternalType1 &A, InternalType2 &Pointvector, InternalType3 &Slicing, amg_tag &tag)
	Calls the right coarsening procedure.
template<typename InternalType1 , typename InternalType2 >
void	amg_influence (unsigned int level, InternalType1 const &A, InternalType2 &Pointvector, amg_tag &tag)
	Determines strong influences in system matrix, classical approach (RS). Multithreaded!
template<typename InternalType1 , typename InternalType2 >
void	amg_coarse_classic_onepass (unsigned int level, InternalType1 &A, InternalType2 &Pointvector, amg_tag &tag)
