	!For strong connection reference:
integer	shape = D_SpMtx_SHAPE_UNDEF
	Undefined, square, rows > columns, columns > rows.
logical	symmstruct = .false.
logical	symmnumeric = .false.
integer	scaling = D_SpMtx_SCALE_UNDEF
	scaling of the matrix
integer	ol0nnz = -1
	This is needed in parallel aggregation case with zero overlap.
integer, dimension(:), pointer	perm_map
	Permutation map for freedoms : perm_map[Mnlf].
integer	subsolve_id
	subsolve id for the coarse matrix
For Arranged Matrix
integer, dimension(:), pointer	M_bound
	Lower bounds for rows/columns which also serve as upper bound for previous value.
integer	arrange_type = -1
Block structure
integer	nblocks = -1
	number of blocks
integer	mtx_inner_bound = -1
	Bound to separate inner nodes.
integer, dimension(:,:), pointer	mtx_bbs
	Subblock start: mtx_bbs[2*nblocks,2*nblocks] For the block (i,j) bs=mtx_bbs(i,j) gives the starting block index 'bs' for 'indi(bs)', 'indj(bs)' and 'val(bs)'.
integer, dimension(:,:), pointer	mtx_bbe
	Subblock end: mtx_bbe[2*nblocks,2*nblocks] For the block (i,j) be=mtx_bbe(i,j) gives the ending block index 'be' for 'indi(be)', 'indj(be)' and 'val(be)'.

logical SpMtx_class::SpMtx::symmnumeric = .false.

 what kind of symmetry? nonzero structure only or numerical symmetry also
 NB: We still assume that all matrices have symmetric
     nonzero structure and posess numerical
     symmetry, which also means that we can
     hold in memory only L or U parts of it.
