/**
* 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 javax.measure.quantity.Length length} and a {@link javax.measure.quantity.Time time} is not allowed by the standard model,
* but is quite valid in a relativistic context.
*
*
*
* Models are {@link javolution.context.LocalContext context-local}, allowing multiple models to be used concurrently. For example:[code]
* LocalContext.enter(); try { RelativisticModel.select(); // Affects the current thread only. ... } finally { LocalContext.exit(); }[/code]
*
*
*
* The names and characteristics of the models are presented in the following table:
