[PEPr] Comment on Web Services::AChecker

Code looks really clean - kudos for that. The documentation is great too! In addition to what Christian said: * I'd implement a fluent interface for all set (__set(), set*(), add*()) methods (currently you return void) * I'd refactor parseRestResponse() * in Services_AChecker_Response, Services_AChecker_Message, ...: I'd rather have get and set methods instead of public variables (personal preference, I guess) * type hinting in addError(), addLikelyProblem(), addPotentialProblem() * added bonus: unit tests :-) -- http://pear.php.net/pepr/pepr-proposal-show.php?id=655
