Base for Quantities (i.e. dimensioned values).
Internal
QBase is the base class for Quantum .
Quantities are values with a unit. Their basic specification can be one of two forms:
Quantity( Double value, String unit); // or: Unit unit Quantum<Type> ( Type value, String unit) // or: Unit unit
See Quantum for details.
To provide the possibilty of mixing units from different Quantum<T1>, Quantum<T2>
