Peter Boyle f8b8e00090 Systematise the accelerator primitives and locate to Grid/threads/Accelerator.h / Accelerator.cc 
Aim to reduce the amount of cuda and other code variations floating around all over the place.

Will move GpuInit iinto Accelerator.cc from Init.cc
Need to worry about SharedMemoryMPI.cc and the Peer2Peer windows
