/**
This class is a simple repository of correspondances between Strings and numbers. It's
intended usage is to ameliorate the brain damage caused by Java's lack of "enum" types.
In truth, it should be used only for objects whose representation you do not control.
For objects you control, it's much better to use static variables derived from
type NamedObject
