/**
  @file postdata.sas
  @brief  Either returns the file diffs or actually loads the data to target
  @details Before loading the target, a check is made against the time the
  target was last updated (backend) and the time the DIFF was generated
  (frontend).  If the target was updated whilst the DIFF was on the screen,
  then the provided diff may have been incorrect and so a new DIFF should be
  generated and approved before load.

  Only 100 rows (of each DIFF type) are displayed on the DIFF screen.
