*  You can run multiple instances of rails server by changing the port number:  rails s -p 3001
*  For learning CSS stuff - http://flukeout.github.io/
*  Assume the following tables:  A table of users, and a table of books.
  **  Outer left join is used for in the following scenario:  If you had users who may have books, an outer left join would allow you to get all the users and their books, if they have them.
  **  Inner join would get all of the users even if they have no books and all of the books even if they have no users.
  **  Full outer join would be all of the users and all of the books whether they have an associated book or user.
*  When :js => true when using Caybara and Javascript, you need to make sure the database is truncation instead of transaction since a separate thread is spun off during testing.
