    // PushLocationProxy gets its location from history API. No hash needed here.
    // Only compatible with Firefox >= Chrom 6, Firefox 4.0, Safari 5.0
    //
    // ### Example
    //
    //     var app = $.sammy(function() {
    //         // set up the location proxy
    //         this.setLocationProxy(new Sammy.PushLocationProxy(this));
    //
    //         this.get('/about', function() {
    //           // Do something here
    //         });
    //
    //     });
    //
    // Clicking on that link would not go to /about, but would set the apps location
    // to 'about' and trigger the route.
    Sammy.PushLocationProxy = function(app) {
        this.app = app;
