      Changed handling of BADFLOAT data: now positions are marked
      bad only if the longitude is BADFLOAT in the input file.
      Hence, a profile can have a valid position (from a gps fix,
      for example), without having valid velocity.

      Added optional output filename prefix.

   adcp/adcpsect/adcpsect.h
      Increased sizes of depth grid arrays to 512, for both
      the ungridded and the regridded data.

   grid/timegrid.c
      Substituted get_time_range() for the scanf call that
      was being used in the main "while" loop.  The
      practical difference is that timegrid will no longer
      fail if it is given a time range with decimal seconds.

   adcp/ping2mat/ping2mat.c
      Merged the Brookhaven National Labs changes into our
      version, so that configuration and bottom track data
      can be output.
