+====== Usage ======
+disp_t: your Dispatchable base class
+implt_t: your implementation class
+
+ObjectFactory<disp_t, impl_t> myFactory;
+impl_t myImplementation;
+
+//....
+
+//during service registration
+myFactory.Register(WASABI2_API_SVC);
+
+//during service deregistration
+myFactory.Deregister(WASABI2_API_SVC);
+
+==== Class requirements ====
+your base or implementation class requires the following three static methods
+static FOURCC getServiceType(); // return your type (e.g. WaSvc::OBJECT)... might already be defined in the dispatchable base class
+static const char *getServiceName(); // return your service name
+static GUID getServiceGuid(); // return your service GUID
