Bio::DB::GFF::Aggregator::none -- No aggregation

       Bio::DB::GFF::Aggregator::none can be used to indicate that you do not want any aggregation performed.
       It is equivalent to providing undef to the -aggregator argument.  It overrides disaggregate() and
       aggregate() so that they do exactly nothing.
