 * Widgets wrapping objects with reflection autopopulation for fast coding
 * 
 * The gwt-jet library provides a fast, flexible and easy way to wrap business 
 * objects that you want to show at the front-end. The jet classes automatically 
 * create the corresponding widget and automagically populate the user modified 
 * values into the original object.
