Automatically reload your node.js app on file change with Gulp (https://github.com/wearefractal/gulp).
// NOTE: I previously suggested doing this through Grunt, but had plenty of problems with
// my set up. Grunt did some weird things with scope, and I ended up using nodemon. This
// setup is now using Gulp. It works exactly how I expect it to and is WAY more concise.
var gulp = require('gulp'),
