   void sc::SCElementKNorm::collect (const Ref< SCElementOp > &) [virtual]
       Multithreaded use of cloneable SCElementOp objects requires that data from cloned objects
       be collected. The default implementation will throw an exception.

       Reimplemented from sc::SCElementOp.

   int sc::SCElementKNorm::has_collect () [virtual]
       If duplicates of the SCElementOp exist (that is, there is more than one node), then if
       has_collect returns nonzero then collect is called with a MessageGrp reference after all
       of the blocks have been processed. The default return value of has_collect is 0 and
       collect's default action is do nothing. If defer_collect member is called with nonzero,
       collect will do nothing (this is only used by the blocked matrices).

       Reimplemented from sc::SCElementOp.

   void sc::SCElementKNorm::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.
