fast_ave_grib2.sh
        Makes a fast average from multiple analyses for forecasts from
        multiple analyses.  The script reads each file one time in sequential 
        order. In addtion, the reads and the processing are done in different 
        processes, so everything runs quite quickly.  Based on web page
