How can I implement gesture recognizers in OS X?

I have done quite a bit with gesture recognizers for iOS, but I am now doing work in OS X, and I am lost.

I want to duplicate the functionality that exists like in Finder where you can two-finger swipe (on your magic mouse) to go back/forward through a directory tree.

I have an NSWindow based app that looks very similar to Finder. I have used apps before that allows you to build your own gesture recognizers so I know it is possible to do it, but I don't see any documentation on it.

What do I need to do to implement these gestures?

Looks like there is also an Event Recognizer class in CZKit. https://github.com/CarterA/CZKit

I haven't used this (yet), so YMMV.

You can read about Handling Trackpad Events in the Cocoa Event Handling guide. The system can detect some pre-defined gestures (swipe, rotate, etc.) or you can listen to the raw touch events, which travel up the NSResponder chain, just like regular mouse events.
