Peter Boyle 357ede3664 Improved FFT -- 1.5-2x when there are 2-6 ranks in a given axis of the cartesian communicator. 
Barrel shift -> all to all (x2) and distributed FFT work fully load balanced without redundant work.
There is little more I can do now on FFT. Comms dominated and running distributed work dividing bandwidth optimal RingAllToAll
