Hotel Advisor  You are in the 2000 year. The Internet is very poor developed. There are no booking and social  services. And you have a great idea... You should develop a prototype of the application, where  users can add a hotels which they have visited and put а rating for them.  Lets start with this simple workflow  1. As a user I can register. As a user I can sign in.  2. As a user I can see a list of hotels.  3. As a user I can add a hotel. Hotel has next attributes:  b. star rating(required)  g. address(different object) ­ country, state,  city, street  4. As a user on hotel details page I can rate a hotel from 1 to 5 with comment.  5. On the landing page display top 5 hotels with the best rating.  If you know your way, skip this step.  Otherwise we are expecting from you to use these gems in project ­ devise, twitter bootstrap,  haml, simple_form, carriervawe, rspec, capybara
