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