UVFLP
Task:  This task flips the order of channels in UV dataset.
       (From GMRT LSB datasets, to flip to having channels
       ordered with increasing frequency, so that they can
       be combined with the corresponding USB dataset, using
       DBCON.) Does not copy any FG tables (since channel
       numbers change).

Adverbs:
  INNAME.....Input UV file name (name).      Standard defaults.
  INCLASS....Input UV file name (class).     Standard defaults.
  INSEQ......Input UV file name (seq. #).    0 => highest.
  INDISK.....Disk drive # of input UV file.  0 => any.
  IN2NAME....Aux. file name. Can be used for any purpose.
  IN2CLASS...Aux. file class
  IN2SEQ.....Aux. file sequence number.
  IN2DISK....Aux. file sequence number.
  OUTNAME....Output UV file name (name).     Standard defaults.
  OUTCLASS...Output UV file name (class).    Standard defaults.
  OUTSEQ.....Output UV file name (seq. #).   0 => highest unique
  OUTDISK....Disk drive # of output UV file. 0 => highest with
             space for the file.
  DOINVERS...User specified switch, to       1 => change,
             change sign of channel width    0 => no change.
             in FQ table (or not). Use 1
             for GMRT LSB datasets.
