public class Power
extends AbstractDoubleScalarRel<PowerUnit,Power>

Easy access methods for the Power DoubleScalar, which is relative by definition. Instead of:

 DoubleScalar.Rel<PowerUnit> value = new DoubleScalar.Rel<PowerUnit>(100.0, PowerUnit.SI);
 

we can now write:

 Power value = new Power(100.0, PowerUnit.SI);
 

The compiler will automatically recognize which units belong to which quantity, and whether the quantity type and the unit used are compatible.
