Adding support for Rust, OCaml, and Racket

Hi Seri,
I still sometimes use your tool to solve problems in my favorite language (Haskell), but I am wondering if you could add support for Rust, OCaml, and Racket.

Cheers,
Mukesh

Hey Mukesh! Yes, support for languages other than TopCoder's official ones is the main selling point for this tool, so I do want to expand. Rust is my next priority, cheers.
