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