 * <p>Initalizes the actual application.
 * The SplashScreen is launching a background thread that calls the initApp() method.
 * You can define the preprocessing variable "polish.classes.ApplicationInitializer"
 * for making this interface redundant (which saves some precious JAR space).
 * In that case you must not implement this interface, e.g.
 * <pre>
 * public class MyMidlet extends MIDlet
 * //#if !polish.classes.ApplicationInitializer:defined
 *    implements ApplicationInitializer, CommandListener
 * //#else 
 *    implements CommandListener
 * //#endif
