[Mpi3-ft] docs on CP/R with RDMA fabrics

[Josh Hursey]

Mike,

I was not on the last teleconf so this might have been covered there,  
but just to make sure I understand the later two proposals you sent.  
You are not proposing any MPI interfaces for checkpoint/restart, but  
just describing how you implemented a transparent solution inside or  
below an MPI implementation. Is that correct?
