+    @class wxNSApplicationDelegate
+    @discussion Implements an NSApplication delegate which can respond to messages sent by Cocoa to change Cocoa's behavior.
+
+    wxCocoa will set a singleton instance of this class as the NSApplication delegate upon startup unless wxWidgets is running
+    in a "plugin" manner in which case it would not be appropriate to do this.
+
+    Although Cocoa will send notifications to the delegate it is also possible to register a different object to listen for
+    them.  Because we want to support the plugin case, we use a separate notification observer object when we can.

+    listen for several events sent by the NSApplication singleton.
+
+    Because there can be any number of notification observers, this method allows wxCocoa to function properly even when it is
+    running as a plugin of some other (most likely not wxWidgets) application.
