/**
* Easy access methods for the LinearDensity FloatScalar, which is relative by definition. An example is Speed. Instead of:
*
* <pre>
* FloatScalar.Rel<LinearDensityUnit> value = new FloatScalar.Rel<LinearDensityUnit>(100.0, LinearDensityUnit.SI);
* </pre>
*
* we can now write:
*
* <pre>
* FloatLinearDensity value = new FloatLinearDensity(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.
