Integrate react with express app and pug template

• Each page will be served the express app (route + view with pug template)
• Each page includes its own javascript from dist folder, which is served as static of the app.
• Scripts in the dist folder are compiled from the public folder by webpack

Available scripts

npm run webpack:watch

Tell webpack to watch any change and recompile the dist

npm run build

Use webpack to build the dist

npm run dev

Start the express server with nodemon. Any change will trigger a restart of the app
