vchoi_fork

[svn-r2710] Purpose:
    Features, kind of.
Description:
    Separated the MPI features test into its own independent
    program so that it can be tested on its own without too
    much HDF5 stuff involved.
    Added automatic removal of temporary test files after
    the tests completed.
    Reduced the size of the dataset dimensions to avoid tripping
    the SGI MPI problems of running out of internal mpi type entries.
Platforms tested:
    O2K -64
