Fold Universality Hutton in Rust

Implementation of Graham Hutton's A Tutorial on the Universality and Expressiveness of Fold in Rust.

TODO

1. While the author claims that fold have the universal property, what does it say when we still need some other constructs to do meaningful computations? For instance, we still need Vec for growable arrays, if-else for logic and basically all other non-fold operations.
2. To that point, how to do if-else using fold?
3. Return a generic Iterator instead of Vec.
