  open_state_file      Keith Cherkauer           April 15, 2000

  This subroutine opens the model state file for output.

  Modifications:
  04-10-03 Modified to open and write to a binary state file.    KAC
  06-03-03 modified to handle both ASCII and BINARY state files.  KAC
  10-02-03 Modified to write statefile as year, month, day rather than
           day, month, year.  This makes it consistent with how the
           file is read by the model.                            KAC
  11-May-04 Modified the statefile name to contain year, month, day
	    rather than day, month, year.  This makes it consistent
	    with the planned release of 4.1.0.			TJB
