I've been using promises a lot lately after my first dance in callback hell.

I have not read (but did skim) any of the specs nor do I intend too. I also find the bedtime stories about
promises cute but far to wordy when I'm in a hurry.

So I decided to type up this for future reference, when next time I chain some promises together and am completly confused as
to why they don't work the way I expect.

Think of promises like an asynchronous try, catch, finally

//This part is useless because the main loop exits before we call app.listen()
db.find(function(err, config) {

  if(err) throw err;
