Implement Ruby Arrays with Rust

[danielpclark]

There are several potential ways to go about this. This blog post A Rusting Rubyist IV: Rust Structs and Arrays in Ruby covers one way of implementing Arrays to and from Rust. But there is also ruby-sys, RuRu, and helix to consider.

Things to consider with external implementations:

• documentation & howtos for implementation
• convenience/compatibility
• flexibility
• consistent development on library (not a ghost project)

I'm going to start out with the blogs way and see how it goes from there.
