Code changes: - In the lookup-based extractionFns, inherit injective property from the lookup itself if not specified. Doc changes: - Add a "Query execution" section to the lookups doc explaining how injective lookups and their optimizations work. - Remove scary warnings against using registeredLookup extractionFns. They are necessary and important since they work with filters and function cascades -- two things that the dimension specs do not do. They deserve to be first class citizens. - Move the "registeredLookup" fn above the "lookup" fn. It's probably more commonly used, so the docs read better this way.
