* Easy access methods for the Money DoubleScalar, which is relative by definition. Instead of:
*
* <pre>
* DoubleScalar.Rel<MoneyUnit> value = new DoubleScalar.Rel<MoneyUnit>(100.0, MoneyUnit.SI);
* </pre>
*
* we can now write:
*
* <pre>
* Money value = new Money(100.0, MoneyUnit.SI);
* </pre>
*
* The compiler will automatically recognize which units belong to which quantity, and whether the quantity type and the unit
* used are compatible.
