Restart node.js and reload Chrome tab(s) when files change

Gulpfile.js

/**
 * This Gulpfile will monitor files and restart node.js 
 * and reload the Chrome browser tab(s) when files changes.
 *
 * Dependencies:
 *  gulp            npm install -g gulp         (obviously as this is a gulp script)
 *  gulp-nodemon    npm install gulp-nodemon
 *  chrome-cli      brew install chrome-cli     (https://github.com/prasmussen/chrome-cli)
 * 
 * Installation
 *  Make sure you have all dependencies
 *  Place this Gulpfile.js in the root of your project
 *
 * Running
 *
 *  Run "gulp" to start node.js. Now when you edit files, node will restart and chrome will 
 *       reload the corrresponding tabs.
