A convergence certificate for the H79 widening operator.
Convergence certificates are used to instantiate the BHZ03 framework so as to define widening operators for the finite powerset domain.

The comparison function for certificates.

or
depending on whether *this is smaller than, equal to, or greater than y, respectively.Compares *this with y, using a total ordering which is a refinement of the limited growth ordering relation for the H79 widening.
