Folks --

I want to play around with an application-specific mesh partitioning that will change during the course of a time-dependent simulation.  (Basically, I want to experiment with using the partitioning of a different parallel data structure to drive the mesh partitioning.)

I think that the main thing that I need to do is to implement _do_partition().  (I will also implement _do_repartition() once the basic _do_partition() is working.)  I was wondering what else needs to be done so that distributed System data are redistributed.  Does this happen automatically when calling Partitioner::repartition(), or is there more to it than that?

I think the System data should be handled by System::reinit() which is be called by EquationSystems::reinit().

OK, so something like:

partiontiner->repartition();
equation_systems->reinit();

and then continue?
