public IndividualAggregator ()
        
        Warning: IndividualAggregator is deprecated since 0.9.5. Use IndividualAggregator.dup.
Create a new IndividualAggregator.
Clients should connect to the IndividualAggregator.individuals_changed signal (or the IndividualAggregator.individuals_changed_detailed signal), then call IndividualAggregator.prepare to load the backends and start aggregating individuals.
An example of how to set up an IndividualAggregator:
  IndividualAggregator agg = new IndividualAggregator ();
  agg.individuals_changed_detailed.connect (individuals_changed_cb);
  agg.prepare ();Folks does not support having more than one IndividualAggregator instantiated at the same time. So it's recommended to use IndividualAggregator.dup instead.
