Overview for Gravey Framework and RATS RIA.

The Gravey 2.5 framework is a set of Javascript include files that support Rich Internet Applications with complete Undo/Redo functionality.
The framework home page is at GRAVEY.ORG.
The "RATS" RIA is a Gravey demonstration application.

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 (Reconcile Account Transactions System) demonstration Single Page Application is built upon these libraries, defining Command objects, Models, Views, Controllers, event handlers, and AJAX requests.
