* instead of forwarding calls to a single function (as an ns3::Callback normally does),
* it forwards calls to a chain of ns3::Callback. TracedCallback::Connect adds a ns3::Callback
* at the end of the chain of callbacks. TracedCallback::Disconnect removes a ns3::Callback from
* the chain of callbacks.
