/**
 * Main User Interface for the PSE Sample Peer Group application.
 * <p/>
 * <p/>Provides access to a wide variety of fun and interesting PSE operations.
 * <p/>
 * <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/>
 * <p/>Real applications should not present users with unavailable options.
