* Removed RestKit from inheritance hierarchy * Mappings are implemented as concrete classes * Mapper is much more flexible & powerful * Much more robust error handling * Serialization is reimplemented as an object mapping operation * Added ability to serialize to JSON natively * Reworked Core Data integration * Simplified the codebase substantially
