create Listed Node concept. My first generic node class is already created - GenericCIEffectNode - specific nodes can be created from a plist file at runtime rather than using subclasses. This makes it much quicker to create all the specific effect classes, and easy to set up GUI menus as well. AppDelegate now supplies a master array of all my node listings, which only has 1 listing for now.
added some blur filters to the listing and tried them out. Will set up a test menu, once filter node creation menus are in place, that sets up a chain input-effect-output for each node in the listing, for easy testing
