Exporting and Binding Remote Objects

Remote objects need to be exported. It makes the object listen on anonymous port for method requests from stub.
Exporting happens automatically if you extend RemoteObject or Activatable. Otherwise you must call UnicastRemoteObject.exportObject or Activatable.exportObject.
You must define a constructor that throws RemoteException (because the base class does).
The object server must have a SecurityManager.
The object must get bound (rebind()).
These last two must be done by a when the server starts.
