* Allow CodingKey conformance to be automatically derived for enums which have no raw type (with no associated values) and which have a raw type of String or Int. * Allow Encodable and Decodable conformance to be automatically derived for classes and structs with Encodable/Decodable properties * Add initial unit tests for verifying derived conformance
