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