Functions
MPI_Comm	dg::mpi_cart_sub (MPI_Comm comm, std::vector< int > remain_dims, bool duplicate=false)
	Call and register a call to MPI_Cart_sub with the dg library.
MPI_Comm	dg::mpi_cart_kron (std::vector< MPI_Comm > comms)
	Form a Kronecker product among Cartesian communicators.
template<class Vector >
MPI_Comm	dg::mpi_cart_kron (Vector comms)
	Convenience shortcut for return mpi_cart_kron( std::vector<MPI_Comm>(comms.begin(), comms.end()));
std::vector< MPI_Comm >	dg::mpi_cart_split (MPI_Comm comm)
	Split a Cartesian communicator along each dimensions.
template<size_t Nd>
std::array< MPI_Comm, Nd >	dg::mpi_cart_split_as (MPI_Comm comm)
	Same as mpi_cart_split but differen return type.
