Crate uord 

A library providing implementations of unordered pairs (or more generally, unordered sets).

This is useful when, for example, you want to create a HashMap that associates data with pairs of things:

let mut map: HashMap<UOrd2<u16>, String> = HashMap::new();
map.insert(UOrd2::new([1, 6]), "1-6".to_owned());
map.insert(UOrd2::new([3, 5]), "3-5".to_owned());
map.insert(UOrd2::new([2, 4]), "2-4".to_owned());

assert!(map.contains_key(&UOrd2::new([1, 6])));

When creating a UOrd, the ordering of the items on creation does not matter, and UOrds created with different initial element orders will be equal to one another.
