13 * Easy access methods for the Mass FloatScalar, which is relative by definition. An example is Speed. Instead of:
14 *
15 * <pre>
16 * FloatScalar.Rel<MassUnit> value = new FloatScalar.Rel<MassUnit>(100.0, MassUnit.SI);
17 * </pre>
18 *
19 * we can now write:
20 *
21 * <pre>
22 * FloatMass value = new FloatMass(100.0, MassUnit.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.
