Jonathan R. Madsen 8eff363ed3 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
