[rust-dev] Exercism.io and Rust

[Steve Klabnik]

Hey Rustics,

One of my collegues started http://exercism.io, a site for people to
work on little code examples and discuss them with other people. It
started out with Ruby, then went to JavaScript, Clojure, Elixir, and
Go.

I started porting them over to HEAD Rust, as well. If anyone else
wants to help with this effort, or make suggestions about how to make
it better, I'd love the help/feedback.

Here's the first set of tests for the first example:

And here's the list of examples
