- in makeFaMesh, the serial fields are now only read on the master process and broadcast to the other ranks. The read+distribute is almost identical to that used in redistributePar, except that in this case entire fields are sent and not a zero-sized subset. - improved internal faMesh checking for files so that the TryNew method works with distributed roots.
