I may end up folding the array and property access into the main repo classes (Application and Web). I don't see much point in hiding the configuration and I'm thinking about a putting in a /framework/config directory at the same level as /src so the application can choose which defaults to use and for them to be easier to merge. Thanks for the feedback.
