[GEMPAK #MIK-474893]: How to use "Enhancement Tables"

Hi George,

In SFMAP you can specify the enhancement table with the LUTFIL variable.  
Enhancement tables are located in the directory $GEMTBL/luts/ and are covered 
in the GEMPAK tutorial at:

https://www.unidata.ucar.edu/software/gempak/tutorial/aesthetics.html#5.2

To define the lutfil requires only the table name (the directory $GEMTBL/luts/ 
is assumed).

So for the UNIDATA_VIS enhancement use the definition

LUTFIL = vis_upc.tbl
