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
