= Representing Quantitative Values =

GoodRelations provides a flexible mechanism for representing quantitative values that has several nice features:
 * 1) It can handle point values and open and closed intervals with one mechanism.
 * 2) It supports arbitrary units of measurement (e.g. kilograms, miles, inches, seconds, decibel, ...).
 * 3) It supports value references, dependencies, and measurement meta-data (e.g. this value was measured at a speed of 80 km/h; this value was determined using the ABCD methodology).
