 * This is probably as good a place as any to put this note, as it applies to

 * appropriate enum types because the latter would nearly quadruple storage
 * requirements (they are stored as int's).  This reduces the usefulness of
 * enum types to their ability to declare index values.  I've also elected to
 * forgo the strong typing capabilities of enum types.  C is not terribly adept
 * at strong typing anyway.
