Refactoring the Rust API

I filed a PR to track this (https://issues.apache.org/jira/browse/ARROW-2521) but thought it was worth raising on the mailing list too. I am running into limitations now of the way that Array is represented as an enum and I am unable to implement List with the current design. When
