[MPI3 Fortran] Sample implementation

Thanks. I'd suggest adding some attribute copy/delete functions,
MPI_Request that is sometimes handled differently than other handles
(you'll have them anyway with MPI_ISEND I guess), and MPI_WTIME, as a
MPI_File is a good example of a handle that is a pointer rather than an
integer in MPICH2, but that's probably too far away from the scope of

Subject: [MPI3 Fortran] Sample implementation
We had a short call because it was just Torsten, Jeff, and Craig
(i.e., one Fortran guy and 2 guys who are interested but not experts).
Craig's going to reach out to the other Fortran experts and ensure
that we're moving forward. He's also going to work on a small sample
implementation to ensure that we're moving in the right direction --
some small wrappers around a handful of functions the ensure that the
concepts are right, it works, etc. With a small enough number of
functions, keeping them updated with the current ideas and discussion
shouldn't be too hard. Additionally, although Craig is likely to do
this work in Open MPI, the code should be more-or-less portable (i.e.,
likely with a little bit of work) to other MPI's to test with.
Here's a list of functions that I suggest (others can be included of
Some non-blocking functions
A function with a string
Functions dealing with function pointers
Along with at least the following pre-defined MPI handles (others can
be included of course):
Function pointer handle
These should be representative enough of the different kinds of types
that we need to deal with.
Did I miss anything?
