Classes referencing each other

I already thought about such a solution, but since
my code has to be compatible with python 2.3, i would
have to use the connected_to = staticmethod(connected_to)
syntax, which bloats the code and makes it quite unreadable.

This solution seems good to me. It won't work for me as it is,
because the structure of the classes is actually a bit more
complex, but it pushed me in the right direction.

Thanks again,
