It returns \c true if succeeded, and false otherwise. If the evaluation fails,
then r contains a term that is simplified as much as possible using the interpretations
available in the model.
When model_completion == true, if the model does not assign an interpretation to a
declaration it will build one for it. Moreover, partial functions will also be completed.
So, if model_completion == true, the evaluator never fails if it doesn't contain quantifiers.
