/**
* Provides support for Dimensional Analysis.
The difference between dimensional models lies in the assumptions each makes and,
in consequence,the operations each permits. For example, the summation
of a {@link org.unitsofmeasurement.quantity.Length length} and a {@link org.unitsofmeasurement.quantity.Duration duration}
is not allowed by the standard model, but is quite valid in a relativistic context.
The names and characteristics of the models are presented in the following table:
