+ * Similar in fuction to the MessageDialog, YesNoDialog poses 
+ * a question, that is answered by selection of either a Yes 
+ * button or a No button.<p>
+ *
+ * Note that the YesNoDialog is a singleton - meaning there is
+ * only one YesNoDialog in existence per applet.  Clients
+ * may obtain the YesNoDialog by invoking getYesNoDialog().<p>
