Add recommendations from google places

Added 3 files to the modules directory:
  -  places-url.js : creates a url based on the query string from the user (specifically uses googles 'textSearch')
  -  get-places.js : makes a request to google places api with places-url
  -  places.js : function that takes a query string from the client and returns a promise with an array of 3 places objects returned from get-places.
