Setting up Express with Express-generator

In this video we will set up our application with the express-generator

Important Note, Please Read:
express-generator has been updated since the creation of this video. It has a few small changes, namely the use of express.json() and express.urlencoded vs bodyParser.json() and bodyParser.urlencoded and the use of the http-errors package for error handling. 
These are all good things and will not break your app. 
Just know that your app.js file will not look 100% like the one that I show in the video.
