Detailed Description

Implements the concept of a constant value with a text label.

This class implements an association between a constant integer value and a text label. It provides a single constructor, accessors for both the value and label, and boolean operators which treat the value as the "key" for comparisons. This allows them to be assembled into dictionaries of unique values. Note, that the labels are not required to be unique but in practice it makes little sense to for them to be otherwise.
