Ruby implementations of the full ENV API.

This crate only implements enough of the ENV API in native code to glue the system APIs to the interpreter. ENV offers a rich, Hash-like API on top of the raw names and values.

This constant contains Ruby source code that implements the remainder of these APIs on top of the core accessors and mutators in this crate.
