ODE objects are not necessarily a pure hierarchy.

You might have a car suspension with a strut connected to the body and to the wheel,
and also a shock absorber connected to the body and to the wheel.  This cannot
be represented in a pure topdown tree.

Hence, I think we'll generally need to give objects some kind of name or
identifier in order that objects can refer back to other objects that they
aren't strictly 'part of'.
