3: cumDeathProbs are not read from file, but are hard-coded in
    Loop::s_cumDeathProb.

4. The costs are not read from file anymore, but are specified in the
    configuration file at 'costs:', reading values for, resp.:
        cost_XM cost_Tomo cost_<2 cost_2-5 cost_>5 cost_biop discount
    (all ints, except for the last, a double.

5. Cf calculateSize: when computing

        _volume = _startVolume *    //Exponential growth of tumorvolume
                pow(2.0, ((womenAge - _preclinAge) / _doublingTimeYear));

    using floats, then for values, resp.
    65.4499, 40, 26.1368 and 0.109376

    _volume is 'inf' when using floats, but in fact (using doubles) it is
    9.34711e+39.

    -> the new version uses doubles, and avoids floats.

6. loop/loop.h:
                // NOTE: in the orig. source density NRs are used: 1..4
                //       here density INDICES are usd: 0..3
                // but when writing the data file (e.g., data-0.txt, original
                // name e.g., women-test-i0.txt) a + 1 correction is
                // currently applied
        bool use(size_t modality);      //+ use this modality

    See also loop/sensitivity1.cc loop/results.cc and densities/biradsidx.cc

7: the 'no tumor' age is computed as -1, not as 0 as reported in the
    original program. See tumor/results.cc. Also see tumor/reset: when there
    is no tumor all ages are reported as -1, and start volume and self-detect
    (diameter) are set to 0

8. To synchronize the output of the current and original program, tumor
    diameters exceeding 1000 mm. are reported as 1001 mm (used to be 'inf')
    (tumor/results.cc)
