Detailed Description

There are a lot of metrics related to a model (a lambda_f) and we don't want fat classes.

The Visitor pattern is ideal to simplify the interface of lambda_f and keep possibility for future expansions (new metrics).

This works quite well since metrics can be implemented in terms of the public interface of lambda_f.
