Nice work, Matt!

Clever trick. I didn't think about doing this before when running QuadProj in serial before.
I just tested it on pleiades on 128 processes on a large nested grid simulation. The run time decreased from 348s to 104s. Very nice. There were no errors, but there were some lingering RECV/SEND debugging messages. Here are the stats on the dataset.
