Order basic subroutines
int	pastixOrderAlloc (pastix_order_t *const ordeptr, pastix_int_t vertnbr, pastix_int_t cblknbr)
	Allocate the order structure.
int	pastixOrderAllocId (pastix_order_t *const ordeptr, pastix_int_t vertnbr)
	Allocate the order structure for a given number of vertices with no cblk, and id permutation.
int	pastixOrderInit (pastix_order_t *const ordeptr, pastix_int_t baseval, pastix_int_t vertnbr, pastix_int_t cblknbr, pastix_int_t *const permtab, pastix_int_t *const peritab, pastix_int_t *const rangtab, pastix_int_t *const treetab)
	Initialize the order structure with the given values.
void	pastixOrderExit (pastix_order_t *const ordeptr)
	Free the arrays initialized in the order structure.
void	pastixOrderBase (pastix_order_t *const ordeptr, pastix_int_t baseval)
	This routine sets the base of the given ordering structure to the given base value.
void	pastixOrderExpand (pastix_order_t *ordeptr, const spmatrix_t *spm)
	This routine expand the permutation arrays and the rangtab when the spm is using multiple dof per unknown.
int	pastixOrderCopy (pastix_order_t *const ordedst, const pastix_order_t *const ordesrc)
	This routine copy a given ordering in a new one.
pastix_order_t *	pastixOrderGet (const pastix_data_t *const pastix_data)
	This routine returns the pointer to the internal order structure to access permutation information.
void	pastixOrderBcast (pastix_order_t *ordemesh, int root, PASTIX_Comm pastix_comm)
	This routine broadcast the ordemesh structure from node root to all the other nodes.
