A simple platform on which Java/Swing desktop applications may be built. This updated version has packaged the entire library into a single JAR file. We have also made the following changes: ToolBarGenerator should now create ButtonGroups properly for state actions. ApplicationContext has accessors for the WindowManager, DockingManager, StatusDisplayer, and ProgressHandler implementations. It defaults to testing the Application's MainView and the MainView's StatusBar, then uses the Lookup, if the MainView and its StatusBar do not implement the desired interfaces. StatusMessage now uses the com.pekinsoft.desktop.error.ErrorLevel instead of the java.util.logging.Level, so that the levels will no longer need to be cast in order to be used.

The newest version!
