sc::SumIntCoor::SumIntCoor(constRef<KeyVal>&)
       The KeyVal constructor.

       coor
           A vector of IntCoor objects that define the summed coordinates.

       coef
           A vector of floating point numbers that gives the coefficients of the summed coordinates.

SumIntCoor is used to construct linear combinations of internal coordinates.

       The following is a sample ParsedKeyVal input for a SumIntCoor object:

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

voidsc::SumIntCoor::add(Ref<IntCoor>&,doublecoef)
       Add a coordinate to the linear combination. coef is the coefficient for the added coordinate.

   voidsc::SumIntCoor::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::IntCoor.
