Detailed Description
       The SetIntCoor class describes a	set of internal	coordinates.

       It can automatically generate these coordinates using a integral
       coordinate generator object (see	the IntCoorGen class) or the internal
       coordinates can be explicity given.

       The following is	a sample ParsedKeyVal input for	a SetIntCoor object.

	 setintcoor<SetIntCoor>: [
	   <SumIntCoor>: (
	     coor: [
	       <StreSimpleCo>:(	atoms =	[ 1 2 ]	)
	       <StreSimpleCo>:(	atoms =	[ 2 3 ]	)
	       ]
	     coef = [ 1.0 1.0 ]
	     )
	   <BendSimpleCo>:( atoms = [ 1	2 3 ] )
	 ]

Constructor & Destructor Documentation
   sc::SetIntCoor::SetIntCoor (const Ref< KeyVal > &)
       The KeyVal constructor.

       generator
	   A  IntCoorGen  object  that	will  be used to generate the internal
	   coordinates.

       i   A sequence of integer keywords, all $i$ for $0   i  <  n$,  can  be
	   assigned to IntCoor objects.

Member Function	Documentation
   virtual    void   sc::SetIntCoor::guess_hessian   (Ref<   Molecule	>   &,
       RefSymmSCMatrix &) [virtual]
       Create an approximate Hessian for this set of coordinates. This Hessian
       is a symmetric matrix whose i'th	diagonal is the	force constant for the
       i'th coordinate in the set.

   void	sc::SetIntCoor::save_data_state	(StateOut &) [virtual]
       Save the	base classes (with save_data_state) and	 the  members  in  the
       same  order  that  the  StateIn	CTOR  initializes  them.  This must be
       implemented by the derived class	if the class has data.

       Reimplemented from sc::SavableState.
