title: What's the difference between this.route() and this.resource()?
body: <p>I understand that routes are used to map URLs to templates, but apparently you could either define routes with this.route or this.resource</p>
  
  <pre><code>App.Router.map(function() {
    this.route("about", { path: "/about" });
    this.route("favorites", { path: "/favs" });
  });
  
  App.Router.map(function() {
    this.resource('posts', { path: '/posts' }, function() {
      this.route('new');
    });
  });
  </code></pre>
  
  <p>Do you just use this.resource if you want to define subroutes to a route or is there another rationale I'm not getting?</p>
