Pending things
 - figure out a better practice to avoid the inclusion of config.test
 - script that will insert the default users to be returned on the /api/players call
 - figure out a better way to :
mongoose.connection.on('error', function(err){
  console.log("connection already opened");
})
mongoose.connect(config.mongo.uri);
 - I don't know and Can't find a descent way. Most of the examples I've found uses the mongoose.connect inside express app function
