• Made the SDK more Ruby-like.
• Merged some pull requests.
• Started generating docs.
• Made the gem follow Semver 2.0.
• Namespaced the class, so it's now WePay::Client.new instead of WePay.new.
• Updated the license from MIT to the more corporate/patent-friendly Apache 2.0.
• Actually gave this release a Git tag (mindblown).
