;#  PROGRAM OVERVIEW:
;#       (1) This program reads in the RAPIDSCAT data from Royal Netherlands Meteorological Institute (KNMI).
;#       (2) The input file is in NEXRAD LEVEL II ASCII format.
;#       (3) The output file is a JPG file.
;#       (4) There are several functions,
;#               -a- -
;#               -b- -
