sigc::track_obj() tracks trackable objects, referenced from a functor.
It can be useful when you assign a C++11 lambda expression or a std::function<> to a slot, or connect it to a signal, and the lambda expression or std::function<> contains references to sigc::trackable derived objects.
The functor returned by sigc::track_obj() is formally an adaptor, but it does not alter the signature, return type or behaviour of the supplied functor.
