Used actual print in #7 abstract function.

Also printed relation in model.
But still this all depends of whatever you see when you print.
No more printing relations in #7 abstract function.

Prints (that use __repr__) already show relations (at least partially).
Merge branch 'master' of github.com:Selrak/AMS601.3
