        If no payment convention is passed, the convention of the
        floating-rate schedule is used.
 
        \warning if <tt>Settings::includeReferenceDateCashFlows()</tt>
                 is set to <tt>true</tt>, payments occurring at the
                 settlement date of the swap might be included in the
                 NPV and therefore affect the fair-rate and
                 fair-spread calculation. This might not be what you
                 want.

        - the correctness of the returned value is tested by checking
          that the price of a swap paying the fair fixed rate is null.
        - the correctness of the returned value is tested by checking
          that the price of a swap receiving the fair floating-rate
          spread is null.
        - the correctness of the returned value is tested by checking
          that the price of a swap decreases with the paid fixed rate.
        - the correctness of the returned value is tested by checking
          that the price of a swap increases with the received
          floating-rate spread.
        - the correctness of the returned value is tested by checking
          it against a known good value.
