      Implementation of the Integration Interface.
      This module defines the general integration auxillaries for Ascend.
      Requires
      #include "tcl.h"
      #include "utilities/ascConfig.h
      #include "general/list.h"
      #include "compiler/instance_enum.h"
      #include "compiler/dimen.h"
      #include "solver/slv_client.h"
      #include "compiler/interface.h"
      #include <stdio.h>   (for current INTEG_DEBUG functions)

      Author:       Boyd T. Safrit
      by Kirk Abbott and Ben Allan
      Created: 1/94
      Version: $Revision: 1.16 $
      Version control file: $RCSfile: Integrators.h,v $
      Date last modified: $Date: 2003/08/23 18:43:06 $
      Last modified by: $Author: ballan $
      Changes:  8/95  Added support code for BLSODE, an
                      experimental user interface
                      which identifies states, derivatives,
                      observations, and tolerances by flags.
                      Interface redesign (ASCEND side) by
                      Jennifer Stokes and (C side) Ben Allan.
                      The only required vector left is that
                      defining the time steps to calculate
                      results at. All state and observation
                      data are (optionally) logged to files.
 /96  Removed old lsode interface routines.
                      The Piela version of lsode is dead.
 /96  Removed the var == instance assumption from
                      the implementation.
