Remove reliance on MPI_Comm_rank (#56)
* Remove reliance on MPI_Comm_rank - read /proc/<PID>/tasks/<PID>/children of parent process to deduce the rank - Old format relied on user calling MPI_Comm_rank(MPI_COMM_WORLD, ...) - if MPI_Comm_rank called with subcommunicators only, multiple ranks would write to same file * Tweak mpi example
