13   * Easy access methods for the Energy FloatScalar, which is relative by definition. An example is Speed. Instead of:
14   * 
15   * <pre>
16   * FloatScalar.Rel&lt;EnergyUnit&gt; value = new FloatScalar.Rel&lt;EnergyUnit&gt;(100.0, EnergyUnit.SI);
17   * </pre>
18   * 
19   * we can now write:
20   * 
21   * <pre>
22   * FloatEnergy value = new FloatEnergy(100.0, EnergyUnit.SI);
23   * </pre>
24   * 
25   * The compiler will automatically recognize which units belong to which quantity, and whether the quantity type and the unit
26   * used are compatible.
