		int	N_subdomains,
		int *	N_subdomains_elems,
		int *	Subdomains_elems,

	)

ddr_create_subdomains to create partitioning scheme with (or without) overlap Depending on the param Mesh_handling partitioning is done locally or globally

Parameters:

	IN	Mesh_id
	IN	Mesh_handling DDC_LOCAL_MESH - creates subdomains only from local mesh DDC_GLOBAL_MESH - creates subdomains from all procs' meshes
	IN	N_subdomains
	OUT	N_subdomains_elems - sizes (in core elements) for each subdomain preferred size: N_subdomains
	OUT	Subdomains_elems - core elements stored in continogus manner for each subdomain preferred size: number of all elements (LOCAL or GLOBAL)
	OUT	Overlap_sizes - number of overlap element for each subdomain preferred size: N_subdomains
	OUT	Subdomains_elems_overlap - elements creating overlap for each subdomain preferred size: same as Subdomains_elems

Returns:

number of created subdomains
