Rules Decorator that returns default rules
when no matches are returned by the wrapped implementation.
This allows default Rule instances to be added to any
existing Rules implementation. These default Rule
instances will be returned for any match for which the wrapped
implementation does not return any matches.
For example,
Rule alpha;
...
WithDefaultsRulesWrapper rules = new WithDefaultsRulesWrapper(new BaseRules());
rules.addDefault(alpha);
...
digester.setRules(rules);
...
when a pattern does not match any other rule, then rule alpha will be called.
WithDefaultsRulesWrapper follows the Decorator pattern.
