Revisions for LINDOP v 2.4
--------------------------

* The USRFUN and USRPAR routines no longer need to return 
  derivative information, which should significantly simplify
  their use.


Revisions for LINDOP v 2.5
--------------------------

* The new plot library Xplot11 is now used.  It's built-in clipping
  and zooming functions allowed the removal of an entire layer
  of routines.

* Colors are now employed to improve the display of information.
  Each individual operating point has a color associated with it.
  Further uses of color will likely be used in future versions.
