chargerlib.CharacterSets

public final class CharacterSets
extends Object

A class to represent the various character sets allowed in Charger. There are two main sets -- one for type labels and the other for referents. The character set for types is a subset of the one for referents. The design of this feature is probably wrong-headed. There should probably be a "stop" list of characters not allowed and then any others are admitted.
