Title: Allow single tap exit & double tap zoom to coexist

By exposing the double tap recognizer, we can require the single tap recognizer to require the double tap recognizer to fail. This allows the double tap zoom feature to still work even when the user has enabled single tap closing. I made this solution for my project but figured I'd offer it as a pull request if you want it.
