Examples of VanillaSwap

org.jquantlib.instruments.VanillaSwap
Plain-vanilla swap @note if you define TodaysPayments like this
```
 new Settings().setTodaysPayments(true); 
```
payments occurring at the settlement date of the swap are included in the NPV, and therefore affect the fair-rate and fair-spread calculation. This might not be what you want. @category instruments @author Richard Gomes
