Merge branch 'update-geogrid-tables' into develop (PR #172)
This merge updates the GEOGRID.TBL files for NoahMP, Fire, and Chem to be
consistent with the GEOGRID.TBL.ARW file, which contains more recent changes.
GEOGRID.TBL.ARW_CHEM is now identical to GEOGRID.TBL.ARW, since the three
additional fields for CHEM, EROD, CLAYFRAC, SANDFRAC were added to
GEOGRID.TBL.ARW in WPS 4.0 for use in Thompson's aerosol-aware microphysics.
* update-geogrid-tables:
update GEOGRID tables for NoahMP, fire and chem
