The tt(iterate) member performs the number of iterations (scenario:
iterations). At each iteration

    it() the random number generator is reset;
    it() the tt(TumorInfo) (cf. section ref(TUMORINFO)) parameters may be

        itt(d_sumDeathAge), the sum of all simulated dying ages over all
            screening rounds;

            round;
        itt(d_modalities), the counters maintained by the used tt(Modalities)
            are reset.

    it() The actual simulation is performed over `scenario nWomen' cases by
        tt(genCases);

        (optionally) written to files (sensitivity, parameters, and rounds
        info, while actually produced simulation data are written to file by
        the tt(genCases) member itself).
