Additional changes include: * Re-wrote the monolithic Controller into separate controller classes that have a more narrow focus. * Implemented common functionality as a `HandlerMethodArgumentResolver` rather than as a helper method in a controller class. * Re-implemented JSONP functionality as an HttpMessageConverter rather than inline within a controller class. * Updated to Jackson 2 for all JSON handling. * By relying on spring-data-commons, spring-data-rest now handles all supported Repository types: JPA, MongoDB, and GemFire. Added support for MongoDB and GemFire repositories by relying on spring-data-commons to provide the metadata rather than maintaining internal metadata information that is store-specific. Replaced Spock spec tests with JMock unit and integration tests. Started integrating Jetty 8 into the testing so MVC testing can be done against a live server.
