// Revision History
//  14 02 01    Remove extra ';'. Also, fixed 10-parameter to make_tuple. (DG)
//  10 02 01    Fixed "null_type" constructors.
//              Implemented comparison operators globally.
//              Hide element_type_ref and element_type_const_ref.
//              (DG).
//  09 02 01    Extended to tuples of length 10. Changed comparison for
//              operator<()
//              to the same used by std::pair<>, added cnull_type() (GP)
//  03 02 01    Initial Version from original tuple.hpp code by JJ. (DG)
