## 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 'Observer::onCreate' when a tool is created, and 'Observer::onRetrieve' 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).
