create location object to handle URL

[Takazudo]

Let's say you create web app. It's like diary or something which based on year-month-day data from URL.

http://example.com/2012/12/27/

Then, I want API like this.

router.route([
    path: /\/([^\/]+)\/([^\/]+)\/([^\/]+)\//, /* ex: /year/month/day/ */
    avoidpagefetch: true,
    insteadpagefetch: function(page, path){
        $('#main').html(pageframehtml);
        var year = path.matchedPathFragments[0];
        var month = path.matchedPathFragments[1];
        var day = path.matchedPathFragments[2];
        callMyApi(year, month, day).done(function(data){
            updateSomethingFromData(data);
            page.trigger('pageready');
        });
    }
]);

I may implement a thing like this.

var loading = new Loading();
router.route([
  path: /\/([^\/]+)\/([^\/]+)\/([^\/]+)\//, /* ex: /year/month/day/ */
  skippagefetch: true,
  pageready: function(location){
    loading.show();
    console.log(location.rip(0)); // year
    console.log(location.rip(1)); // month
    console.log(location.rip(2)); // day
    callAjaxApiOrSomething(year, month, day).done(function(data){
      renderViewOrSometing(data).done(function(){
        loading.hide();
      });
    });
  });
]);

This may be enough because non-history-supported browser can handle only pageready. All we need here seems the location object above.

Location object needs to handle get values like below, too.

http://example.com/foobar/?foo=bar

I need to parse the value like above in URL routing.
Davis.js handles this. But we need to handle it even if the user can't use history.pushState.
