Not that I have the time to do this right now, but the idea would be to 
do most/all of this "behind the scenes," so that application codes that 
use standard SAMRAI PatchData types would work without modification.

One benefit of doing this could be easier access to different smoothers 
for use in FAC; or to other composite-grid solvers for problems where 
FAC is not necessary.  Another might be easier access to CUDA.
