hdf5_msb

[svn-r939] Purpose:
    New Feature

Solution:
    This is a tester for the h5toh4 converter.  It is implemented
    on different HDF5 files to produce HDF4 files.  After each HDF4
    file is produced,  the file is run through the HDF4 dumper hdp.
    The dumper results are compared with expected results and any
    differences are noted.

    Note: The "/hdf4/bin" directory needs to be part of the tester's
    $PATH.

Platform tested:
    Solaris2.5, HP10.20
