  /** IntegralEvaluatorFactory_impl implements a component interface for
      coordinate-aware chemistry models.

      This is an implementation of a SIDL interface.
      The stub code is generated by the Babel tool.  Do not make
      modifications outside of splicer blocks, as these will be lost.
      This is a server implementation for a Babel class, the Babel
      client code is provided by the cca-chem-generic package.

      For use directly in a framework, the parameter port recognizes
      the following parameters:
      <dl>

      <dt><tt>double grad_rms</tt><dd> RMS gradient convergence criterion.
      The default is 0.00030.

      <dt><tt>double grad_max</tt><dd> Max gradient convergence criterion.
      The default is 0.00045.

      <dt><tt>double disp_rms</tt><dd> RMS displacement convergence criterion.
      The default is 0.00120.

      <dt><tt>double disp_max</tt><dd> Max displacement convergence criterion.
      The default is 0.00180.
 
      <dt><tt>bool multiple_guess_h</tt><dd> Whether a new guess Hessian is 
      computed each time <tt>guess_hessian_sovle()</tt> is called.
      The default is true.

      <dt><tt>bool use_current_geom</tt><dd> Whether the guess Hessian is 
      computed at the current geometry or the geometry of the first correction
      pair.  Only meaningful if <tt>multiple_guess_h = true</tt>.
      The default is false.

      <dt><tt>string coordinate_type</tt><dd> Type of coordinates to use for
      optimization: <tt>cartesian</tt>, <tt>symmetrized</tt>, or 
      <tt>redundant</tt>.  The default is <tt>symmetrized</tt>.

      <dt><tt>string extra_bonds</tt><dd>  Vector specifying centers between
      which bonds should be added.  There is no default.

      </dl>

      These parameters must be set by the client for embedded use.
