Final Step: Small fix to allow "deep linking" from bookmarked project (e.g.http://localhost:3000/#/projects/3) to actual project. Also a small fix to correct bug in toggle styles

final-main.js

// Just a small addition to show method
AppRouter = Backbone.Router.extend({

  // ...

  show: function(id) {
     // Seem to have to reconstruct HomeView to allow "deep-linking"
    new HomeView();            
    this.toggleStyles(id);
    project = projectList.get(id);
    new ProjectView({model: project});
  },

  // ...
  
  toggleStyles: function(e) {
    $(".project.btn.btn-info").removeClass("btn-info");
    $('a[href$="projects/' + e + '"]').addClass("btn-info");
  }
        
});
