        If an antenna number is missing from an AN file, some bad
        things happen.  Fixed:
        UVFLG    The translation of station name to number used min
                 match so a 0-length string matched all.  Station
                 names should be an exact match.
        DTSUM    It greatly confused antenna number and count.
                 Rewrote handling of antenna number so that true
                 antenna number if recognized.  Reads all data once
                 through to get which antennas actually appear in the
                 data somewhere.  Those are then printed.  It can
                 optionally print the total summary, optionally
                 followed by the scan-by-scan summary.  Added controls
                 of this printing and of the number of digits used.
                 Changed scaling to avoid overflows to be a simply
                 right shift of the counts (with rounding).  help file
                 updated for options.
        Moved nowhere.
