+New: The template variable Utilities::MPI::mpi_type_id_for_type
+provides information about the `MPI_Datatype` that corresponds to a
+given type. This information is necessary in all MPI calls where one
+needs to provide an `MPI_Datatype` to identify the kinds of objects
+stored in a send or receive buffer.
