app.js should support arguments

[Glavin001]

See http://stackoverflow.com/a/4351548/2578205 Sample Node.js code:

// print process.argv
process.argv.forEach(function (val, index, array) {
  console.log(index + ': ' + val);
});

Sample usage: node app -p 80 Results in

0: node
1: /Users/glavin/Documents/Project Dev/smucs/app
2: -p
3: 80
Express server listening on port 8080
