20011030: using stnplt to add a TC marker

Andrew,
My suggestion was to create a "STATION TABLE" for plotting
with STNPLT. A station table looks like the
tables found in $GEMTBL/stns. See the GEMPAK help
information for more information on STNPLT.
Since you created a surface format gempak file,
you can plot the observation locations using the MARK variable
in the SFPARM parameter using SFMAP like:
SFPARM = mark:23:3:6
where the : characters separate the marker number, size and width.
Use the COLOR parameter to control the marker color.
