Overview for the Gravy framework and RATS WebApp.

The Gravy framework is a set of Javascript include files that implement model-view-controller support classes.

This library supports Rich Internet Application (RIA) code in the browser using the Model-View-Controller design pattern supported by Observer, Command, Bean, Composite, etc. design patterns.

The AJAX classes supports asynchronous REST-style web service requests for XML data that is transformed into Javascript data via XSL and is all executed in the browser. The server merely accepts REST-style requests for data CRUD operations.

The RATS demonstration Single Page Application is built upon these libraries, defining Command objects, Models, Views, Controllers, event handlers, and AJAX requests.
