-  // The DefaultLocationProxy is the default location proxy for all Sammy applications.
-  // 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.

-    // or not to proceed with execution by not invoking `callback` or,
-    // more usefully wrapping callback inside the result of an asynchronous execution.
-    //
-    // ### Example
-    //
-    // The most common use case for around() is calling a _possibly_ async function
-    // and executing the route within the functions callback:
-    //
-    //      var app = $.sammy(function() {

-    //              if (json.login) {
-    //                // show the user as logged in
-    //                current_user = json;
-    //                // execute the route path
-    //                callback();
-    //              } else {
-    //                // show the user as not logged in
-    //                current_user = false;
-    //                // the context of aroundFilters is an EventContext
-    //                this.redirect('#/login');
-    //              }
-    //            });

-    //            callback();
-    //          }
-    //        };
-    //
-    //        this.around(checkLoggedIn);
-    //
-    //      });

-
-    // Adds a onComplete function to the application. onComplete functions are executed
-    // at the end of a chain of route callbacks, if they call next(). Unlike after,
-    // which is called as soon as the route is complete, onComplete is like a final next()
-    // for all routes, and is thus run asynchronously
-    //
-    // ### Example
-    //
-    //      app.get('/chain',function(context,next) {
-    //          console.log('chain1');
-    //          next();
-    //      },function(context,next) {

-    //          console.log('link2');
-    //          next();
-    //      });
-    //
-    //      app.onComplete(function() {
-    //          console.log("Running finally");
-    //      });
-    //
-    // If you go to '/chain', you will get the following messages:
-    //
-    //      chain1
-    //      chain2
-    //      Running onComplete
-    //
-    //
-    // If you go to /link, you will get the following messages:
-    //
-    //      link1
-    //      link2
-    //      Running onComplete
-    //
-    //
-    // It really comes to play when doing asynchronous:
-    //
-    //      app.get('/chain',function(context,next) {
-    //        $.get('/my/url',function() {
-    //          console.log('chain1');
-    //          next();
-    //        });
-    //      },function(context,next) {
-    //        console.log('chain2');

-    // Helpers extends the EventContext prototype specific to this app.
-    // This allows you to define app specific helper functions that can be used

-    //
-    //     var app = $.sammy(function() {

-    //       helpers({
-    //         upcase: function(text) {

-    //         $('#main').html(upcase($('#main').text());
-    //       }});
-    //
-    //     });

-    // Helper extends the event context just like `helpers()` but does it
-    // a single method at a time. This is especially useful for dynamically named

-    //     // Trivial example that adds 3 helper methods to the context dynamically
-    //     var app = $.sammy(function(app) {
-    //
-    //       $.each([1,2,3], function(i, num) {

-    //         this.helper2(); //=> I'm helper number 2
-    //       });
-    //     });
-    //
-    // ### Arguments
-    //
-    // * `name` The name of the method

-    //     $(function() { // document.ready

-  // `partial()` which all return `RenderContext` objects.
-  //
-  // `RenderContext` methods always returns a modified `RenderContext`
-  // for chaining (like jQuery itself).
-  //
-  // The core magic is in the `then()` method which puts the callback passed as
-  // an argument into a queue to be executed once the previous callback is complete.
-  // All the methods of `RenderContext` are wrapped in `then()` which allows you
-  // to queue up methods by chaining, but maintaining a guaranteed execution order
