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

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