       The generator of isotopologues sorted by their probability of occurrence.

       The subsequent isotopologues are generated with diminishing probability, starting from the mode. This
       algorithm take O(N*log(N)) to compute the N isotopologues because of using the Priority Queue data
       structure. Obtaining the N isotopologues can be achieved in O(N) if they are not required to be spit out
       in the descending order.

boolIsoSpec::IsoOrderedGenerator::advanceToNextConfiguration()[final],[override],[virtual]
       Advance to the next, not yet visited, most probable isotopologue.

       Returns
           Return false if it is not possible to advance.

       Implements IsoSpec::IsoGenerator.
