Namespaces
namespace	oomph
	DRAIG: Change all instances of (SPATIAL_DIM) to (DIM-1).
namespace	oomph::METIS
	Namespace for METIS graph partitioning routines.

Typedefs
typedef void(*	oomph::METIS::ErrorToWeightFctPt) (const double &spatial_error, const double &max_error, const double &min_error, int &weight)
	Typedef for function pointer to to function that translates spatial error into weight for METIS partitioning.

Functions
	oomph::METIS_API (int) METIS_PartGraphKway(idx_t *
	Metis graph partitioning function.
void	oomph::METIS::default_error_to_weight_fct (const double &spatial_error, const double &max_error, const double &min_error, int &weight)
	Default function that translates spatial error into weight for METIS partitioning (unit weight regardless of input).
void	oomph::METIS::uniform_partition_mesh (Problem *problem_pt, const unsigned &ndomain, Vector< unsigned > &element_domain)
	Partition mesh uniformly by dividing elements equally over the partitions, in the order in which they are returned by problem. On return, element_domain[ielem] contains the number of the domain [0,1,...,ndomain-1] to which element ielem has been assigned.
void	oomph::METIS::partition_mesh (Problem *problem_pt, const unsigned &ndomain, const unsigned &objective, Vector< unsigned > &element_domain)
	Use METIS to assign each element to a domain. On return, element_domain[ielem] contains the number of the domain [0,1,...,ndomain-1] to which element ielem has been assigned.
void	oomph::METIS::partition_mesh (OomphCommunicator *comm_pt, Mesh *mesh_pt, const unsigned &ndomain, const unsigned &objective, Vector< unsigned > &element_domain)
	Use METIS to assign each element to a domain. On return, element_domain[ielem] contains the number of the domain [0,1,...,ndomain-1] to which element ielem has been assigned.
void	oomph::METIS::partition_distributed_mesh (Problem *problem_pt, const unsigned &objective, Vector< unsigned > &element_domain_on_this_proc, const bool &bypass_metis=false)
	Use METIS to assign each element in an already-distributed mesh to a domain. On return, element_domain_on_this_proc[e] contains the number of the domain [0,1,...,ndomain-1] to which non-halo element e on THE CURRENT PROCESSOR ONLY has been assigned. The order of the non-halo elements is the same as in the Problem's mesh, with the halo elements being skipped.
