Important notes to the user:

- The Java mechanisms to protect against malicious code limit access to the file system on the host computer. For this reason, it is not possible to use the "Open", "Save", or "Save As" features of this demonstration - attempting to do so will result in an error dialog. (This will also happen if an attempt is made to save a file when performing a GUI window close or "Quit" operation.)
- "Print" will send its output to the Java console; how to access this depends on the brower.
- Closing the window or "Quit" will close the window, but will not, of course, actually quit out of the browser - hence what will be left is a blank page with no window showing. Reloading the page should restart the program - though this may be browser dependent.
