title: Session is not defined in Express
body: <p>I've included the cookie-parser before the session (not sure if needed with the current versions), imported express-session as visible. If I change <code>session</code> to <code>express.session</code> on line 8 I get a deprecation error (not warning).</p>
  
  <pre><code>var express = require('express'),
      cookieParser = require('cookie-parser'),
      expressSession = require('express-session'),
      port = process.env.PORT || 3000;
  
  app = express();
  
  app.use(cookieParser());
  app.use(session({
      secret: "yadayada",
      resave: true,
      saveUninitialized: true
  }));
  
  app.get('/', function (req, res) {
      console.log(req.session);
      console.log(req.cookies);
  });
  
  app.listen(port);
  </code></pre>
