  the parfile discussion

* Leo asked about how to finely control what SYNC does, specifically
  looking for a way to exchange ghost zones but does not transfer
  information 
** no function to do just ghost zone exchange
** could use EnableProlongation / DisableProlongation (in
Carpet/interface.ccl)

adjusting by volume
