window.App = Backbone.Router.extend({

  initialize: function(){ 
    this.route(/^$/, 'mainPage');
  }

  mainPage: function(){
    console.log("Showing main page...");

    var content = $('#content');

    content.empty();

    var menuView = new MenuView();
    content.append(headerMenuViews.render().el);
    
    var mainContentView = new MainContentView({
      model: someModel
    });
    content.append(mainContentView.render().el);

    //You can also append the content of one or more views to a DIV
    var specialPlaceOnPage = $("<div></div>").appendTo(content);

    var fooView = new FooView();
    specialPlaceOnPage.append(fooView.render().el);

    var barView = new BarView();
    specialPlaceOnPage.append(barView.render().el);
