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