Jennie,

re: update on gribdec.k decoding of SHUM grib files from NCAR

The copies of the tables being used by gribdec.k are in ~mccode/mcidas/data.
This is the MCDATA directory for the user 'mccode' and, rightfully, is
the first directory in its MCPATH.  The ordering in MCPATH determined
that these tables be used in the decoding.

Yes, it is already done in ~mccode/mcidas/data/gbtbpds001.2vx.

>(next week), so its not a big deal right now.

OK.
