          The TR1
          Tuple provides the get
          function to provide access to it's elements by zero based numeric index.
        
template<int I, T> RJ get(T& t);
          Requires: 0
          < I
          <= N.
          The program is ill formed if I
          is out of bounds. T is
          any fusion sequence type, including tuple.
        
          Return type: RJ
          is equivalent to result_of::at_c<I,T>::type
          Returns: A reference to the Ith element of T.
        
template<int I, typename T> PJ get(T const& t);
          Requires: 0
          < I
          <= N.
          The program is ill formed if I
          is out of bounds. T is
          any fusion sequence type, including tuple.
        
          Return type: PJ
          is equivalent to result_of::at_c<I,T>::type
          Returns: A const reference to the Ith element of T.
