Detailed Description

       CartesianIter gives the ordering of the Cartesian functions within a shell for the
       particular integrals specialization.

Member Function Documentation

   int sc::CartesianIter::bfn () [inline]
       Returns the number of the current basis function within the shell. This starts at 0 and
       sequentially increases as next() is called.
