Module attribute 

Attribute caching on communicators. Mirrors rsmpi’s attribute module: a keyval identifies a slot, and arbitrary typed values can be cached on a communicator and retrieved later.

use mpi::attribute::{create_keyval, CommunicatorAttributes};
let key = create_keyval();
world.set_attr(&key, 123u64);
assert_eq!(world.get_attr::<u64>(&key), Some(123));
