// CALL THE PACKAGES --------------------
var express    = require('express'); 	   // call express
var app        = express(); 		   // define our app using express

var mongoose   = require('mongoose'); 	   // for working w/ our database

// BASE SETUP
// ==========================

// APP CONFIGURATION ----------------------------
