Public Member Functions
	RLDLTKernel ()
	Default constructor, initializes to 0 size.
	RLDLTKernel (LowerMatrixRange< Precision > &A)
	Seats reference to L, to be factor()'d later.
	RLDLTKernel (LowerMatrixRange< Precision > &A, InputStream &in)
	Constructs from an InputStream, after seating reference to L.
void	write (OutputStream &out) const
	Writes to an OutputStream.
uint64_t	factor ()
	Factors A = L*I*L'.
uint64_t	solveL (const MatrixRange< Precision > &B, char side, char op) const
	Solves op(L)*X=B or X*op(L)=B, overwrites B with X.
void	solveI (const MatrixRange< Precision > &B, char side) const
	Solves I*X=B or X*I=B, overwrites B with X.
std::pair< int, int >	inertia () const
	Returns inertia I, (n_plus, n_minus). Useful for schur downdates.
int	size () const
	Size inspector.
