viklev1 - Create calibrated Viking Oriter Level 1 images
VIKLEV1 ia a TAE procedure that calls PERL scripts to perform the
level 1 processing sequence on a Viking Orbiter PDS image.  This
includes image cleanup, finding and removal of reseaus, and
radiometric calibration.

The user has the choice to run one image at a time using the FROM
parameter or multiple files through a single column ascii file
that contains file names for the (FROMLIST parameter). The file
names in the ascii file MUST HAVE ".cub.lev0" for the file extension.

Output file names are built from the 'root' name with the '.lev0.cub'
extension "stripped" off and replaced with '.lev1.cub'.

ADDITIONAL NOTES:

Parm	Description
FROM	Input file name ".lev0.cub" extension required
FROMLIST	List of input files names, each filename listed must have ".lev0.cub" as the extension.
ACTION	There are 2 ways the program can remove the Reseaus. BILINEAR will use bilinear interpolation to create new DN values for the pixels inside the SDIM x LDIM box. NULL will simply replace each DN value inside the SDIM x LDIM box with the ISIS NULL value. The NULL option will allow the user to run another filter program such as "boxfilter" to replace the NULL values.
SDIM	Number of samples to remove around each Reseau location. The area inside the SDIM x LDIM box will be changed to remove the Reseau. If the number entered is not an odd number, 1 will be added to it to make the dimension an odd number. Default is 9.
LDIM	Number of lines to remove around each Reseau location. The area inside the SDIM x LDIM box will be changed to remove the Reseau. If the number entered is not an odd number, 1 will be added to it to make the dimension an odd number. Default is 9.
