public class Frequency
extends AbstractDoubleScalarRel<FrequencyUnit,Frequency>

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

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

we can now write:

 Frequency value = new Frequency(100.0, FrequencyUnit.SI);
 

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