                die between last step unit time and current  step unit time, 
                which is also equal to probability to die before dh 
                minus probability to die before dh-stepm . 
                In version up to 0.92 likelihood was computed
                as if date of death was unknown. Death was treated as any other
                health state: the date of the interview describes the actual state
                and not the date of a change in health state. The former idea was
                to consider that at each interview the state was recorded
                (healthy, disable or death) and IMaCh was corrected; but when we
                introduced the exact date of death then we should have modified
                the contribution of an exact death to the likelihood. This new
                contribution is smaller and very dependent of the step unit
                stepm. It is no more the probability to die between last interview
                and month of death but the probability to survive from last
                interview up to one month before death multiplied by the
                probability to die within a month. Thanks to Chris
                Jackson for correcting this bug.  Former versions increased
                mortality artificially. The bad side is that we add another loop
                which slows down the processing. The difference can be up to 10%
                lower mortality.
