 * <code>RouterCatchAllStrategy</code> is a strategy interface that allows developers to hook in custom code when
 * an event is being routed on the inbound or outbound but does not match any of the criteria defined for the routing.
 *
 * Think of catch all strategies as a safety net for your events to ensure that all events will get processed.  If you
 * do not use conditional routing logic, you will not need a catch all strategy.
