angular.module('myBeerApp.services', ['ngResource']).
  value('version', '0.1').
  factory('beerDB', function($resource) {
    return $resource('URL',{
      alt:'json',
      appToken:'TOKEN',
      q:'rock',
      callback: 'JSON_CALLBACK'
    },
      {
        get: {
          method:'JSONP',
          headers: {
            'Content-Type': 'application/json',
            'Accept': 'application/json'
            }
