NGroup0                 NGroup0 computes the group numbers of
                        recreation areas where all the sequence(s) of
                        their presences (1) on the combination of
                        activities pattern and time segment are NOT
                        interrupted by absences (0). Thus in this case
                        we have 1 group of ones (presences).
NGroup1                 NGroup1 computes the group numbers of
                        recreation areas where all the sequence(s) of
                        their presences (1) on the combination of
                        activities pattern and time segment are only
                        once interrupted by their absence (0). Thus in
                        this case we have two groups of ones
                        (presences).
NGroup2                 NGroup2 computes the group numbers of
                        recreation areas where all the sequence(s) of
                        their presences (1) on the combination of
                        activities pattern and time segment are only
                        twice interrupted by their absences (0). Thus
                        in this case we have three groups of ones
                        (presences).
NGroup3                 NGroup3 computes the group numbers of
                        recreation areas where all the sequence(s) of
                        their presences (1) on the combination of
                        activities pattern and time segment are three
                        times interrupted by absences (0). Thus in this
                        case we have four groups of one (presence).
NGroup4                 NGroup4 computes the group numbers of
                        recreation areas where all the sequence(s) of
                        their presences (1) on the combination of
                        activities pattern and time segment are four
                        times interrupted by absences (0). Thus in this
                        case we have five groups of one (presences).
