Concepts
concept	mpi::Serializable
	A concept that checks if objects of a type can be serialized and deserialized.

Functions
template<Serializable T>
MPI_Datatype	mpi::get_mpi_type (const T &obj)
	Create an MPI_Datatype from a serializable type.
template<typename... Ts>
MPI_Datatype	mpi::get_mpi_type (std::tuple< Ts... > tup)
	Create a new MPI_Datatype from a tuple.

Variables
template<typename T, typename = void>
constexpr bool	mpi::has_mpi_type = false
	Type trait to check if a type T has a corresponding MPI datatype, i.e. if mpi::mpi_type has been specialized.
template<typename T>
constexpr bool	mpi::has_mpi_type< T, std::void_t< decltype(mpi_type< T >::get())> > = true
	Specialization of mpi::has_mpi_type for types which have a corresponding MPI datatype.
