+  // A location proxy is a prototype that conforms to a simple interface. The purpose
+  // of a location proxy is to notify the Sammy.Application its bound to when the location
+  // or 'external state' changes.
+  //
+  // The `DefaultLocationProxy` watches for changes to the path of the current window and
+  // is also able to set the path based on changes in the application. It does this by
+  // using different methods depending on what is available in the current browser. In
+  // the latest and greatest browsers it used the HTML5 History API and the `pushState`
+  // `popState` events/methods. This allows you to use Sammy to serve a site behind normal
+  // URI paths as opposed to the older default of hash (#) based routing. Because the server
+  // can interpret the changed path on a refresh or re-entry, though, it requires additional
+  // support on the server side. If you'd like to force disable HTML5 history support, please
+  // use the `disable_push_state` setting on `Sammy.Application`. If pushState support
+  // is enabled, `DefaultLocationProxy` also binds to all links on the page. If a link is clicked
+  // that matches the current set of routes, the URL is changed using pushState instead of
+  // fully setting the location and the app is notified of the change.
+  //
+  // If the browser does not have support for HTML5 History, `DefaultLocationProxy` automatically
+  // falls back to the older hash based routing. The newest browsers (IE, Safari > 4, FF >= 3.6)
+  // support a 'onhashchange' DOM event, thats fired whenever the location.hash changes.
+  // In this situation the DefaultLocationProxy just binds to this event and delegates it to

+  // an argument into a queue to be executed once the previous callback is complete.
