[Mpi3-tools] MPIT 3.1: look up by name

[Jeff Squyres (jsquyres)]

Is this just a convenience function?

I ask because all it effectively does is move the loop looking for the variable down to the MPI_T layer.

All restrictions and requirements for MPI_T_CVAR_GET_INFO are the same for MPI_GET_CVAR_INFO_NAMED except that the cvar_index is now returned from the function, and name is an input.
