Detailed Description

allow call-backs when a tool is a created or retrieved

   class myObserver : public ITooSvc::Observer {
        void onCreate(IAlgTool& tool) {
            cout << "tool " << tool.name() << " created " << endl;
        }
        void onRetrieve(IAlgTool& tool) {
            cout << "someone requested " << tool.name() <<endl;
        }

   }

   myObserver *observer = new myObserver;
   IToolSvc* svc = ...
   svc->registerObserver(observer);

IToolSvc implementations will call 'ObserveronCreate' when a tool is created, and 'ObserveronRetrieve' if a tool is retrieved.

The user is responsible of the life time of the object and must un-register it before it is deleted (e.g. during the finalization).
