Adding Hammer.js to get swipe gesture quickly. This is overkill considering I pretty much only need swipe for this app but its a quick solution for now. Would love to implement a simple Hammer that does less (Hammer is 4000 lines unminified). Also added Touch Adapter class to wrap Hammer impl so I can use sometihng ele later more easily. Modified ViewAdapter and ViewController to handle swipes. Still looking for the optimum Observer implementation (pub/sub vs Event D vs Signals). Will be trying a Dispatcher helper solution that delegates prototypical inheritance of EventDispatcher.js.
