    //  range_run
    //
    //      An implementation of a sparse bit (boolean) set. The set uses
    //      a sorted vector of disjoint ranges. This class implements the
    //      bare minimum essentials from which the full range of set
    //      operators can be implemented. The set is constructed from
    //      ranges. Internally, adjacent or overlapping ranges are
    //      coalesced.
    //
    //      range_runs are very space-economical in situations where there
    //      are lots of ranges and a few individual disjoint values.
    //      Searching is O(log n) where n is the number of ranges.
    //
