cleanup around filter and predicates : remove duplicate compiler.util.NodeIterators add contains to NodeIterable support isNotA(Class).nor(Class) filtering support filtering on interfaces remove and/or(Class) from FilteredNodeIterable replace with isA(Class).or(Class) lower the cost on extending NodeIterable (remove the until field) NodeList is a NodeIterable Use NodeIterable functions where possible
