[GEMPAK #NFS-589556]: Looping VGF files in NMAP

Kwan,

It is not necessary to have grids in different grid files. The datatype.tbl file
will provide a template that tells gempak how to access the data files, and 
whether to find forecast or analysis grids in the file. The mod_res.tbl file 
column 4 will be the model name used to reference the data set in datatype.tbl 
for
accessing the data.

The mod_res.tbl file contains the path to the restore file (a gdplot2 nts type
of file) that defined how to plot the data. For NMAP2 to match the times,
you should not have a GDATTIM set in your restore file.
