Yes. Only the data structures that live in spaces are copied, everything else
is just an ordinary C++ data structure. You'll have to create the Stop object
on the heap using new and keep track of it yourself.

Yes, you'll have to create a stop object that encapsulates several other stop
objects. For an example, see the Cutoff class in gecode/driver/script.hh.
