-/**
- * A helper class for properties of Box which require special
- * handling.
- *
- * To avoid excessive use of String.equals(), the Box.get() and
- * Box.put() methods employ a Hash keyed on property names that
- * require special handling. The value stored in the Hash is an
- * instance of an anonymous subclass of SpecialBoxProperty, which knows
- * how to handle get()s and put()s for that property name. There
- * should be one anonymous subclass of SpecialBoxProperty for each
- * specially-handled property on Box.
