+    A System Tray Icon courtesy of pystray and your friends at PySimpleGUI
+    
+    Import the SystemTray object with this line of code:
+    from psgtray import SystemTray
+
+    Key for the system tray icon is: 
+        tray = SystemTray()
+        tray.key
+        
+    values[key] contains the menu item chosen.
+    
+    One trick employed here is to change the window's event to be the event from the System Tray.
