Until now, for each EventTypeEnum, we have created a corresponding subclass of the class Event.  However, if the event has no event specific information, there is really no need to create a subclass of the class Event.  So, a method has been added to EventManager named sendSimpleEvent(const EventTypeEnum::Enum) that is available for sending these types of events.  EventManager::sendSimpleEvent() does contain a switch statement on every EventTypeEnum so that the method can only be used on specific EventTypeEnum's.
