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