Express App with Handlebar Templating Engine

1. Do a Clean Install of an Express App, or use a boilerplate by lazd
   • Caveat: Express uses Jade as the default tempalting engine
2. Replace Jade with Handlebars (hbs)
   • Why? then you can use the same templating engine for both frontend and backbend
   1. Install Express.js view engine for handlebars.js
      • use --save-dev to automatically save to package.json file
   2. [Use partials](Express.js view engine for handlebars.js) (instruction at bottom of page)
   3. Use Extend and Block helper functions - helper function definitions and sample views
