 *
 *  <p/>This user interface is appropriate for this sample application but is
 *  not appropriate for real applications. The major difference is the strategy
 *  used for dynamically updating buttons and panels. After some experimentation
 *  and feedback it was decided that this application would not dynamically
 *  enable and disable most buttons. By leaving all buttons enabled, but
 *  including status messages when unavailable options are attempted developers
 *  can better experiment and understand why the application behaves as it does.
 *
 *  <p/>Real applications should not present users with unavailable options.
