/**
 * 
 This interface represents any type of quantitative properties or 
 *     attributes of thing. Mass, time, distance, heat, and angular separation 
 *     are among the familiar examples of quantitative properties.
 *     
 * 
 Distinct quantities have usually different physical dimensions; although 
 *     it is not required nor necessary, for example {@link Torque} and 
 *     {@link Energy} have same dimension but are of different nature 
 *     (vector for torque, scalar for energy).
