Add an example of a union-find data structure, using ghost code. Adapted from the why3 proof at https://github.com/ocaml-gospel/vocal/blob/main/proofs/why3/UnionFind_impl.mlw.
Note that it uses the
compute_in_goaltactic in order to unwrap the definition of the invariant. Fortunately one can set it in thewhy3find.jsonfile when using why3find, and everything passes automatically.
