 * Easy access methods for the %Type% FloatScalar. Instead of:

 * <pre>
 * FloatScalar.Rel&lt;TemperatureUnit&gt; value = new FloatScalar.Rel&lt;TemperatureUnit&gt;(100.0, TemperatureUnit.SI);
 * </pre>
 * 
 * we can now write:

 * FloatTemperature value = new FloatTemperature(100.0, TemperatureUnit.SI);
 * </pre>
 * 
 * The compiler will automatically recognize which units belong to which quantity, and whether the quantity type and the unit
