  #         By default it adds the name of the application, the current 
  #         controller and the action
  #
  # classes - Arbitrary class names that are appended. Can be an Array
  #           of Strings or Symbols, or a single String or 
  #           Symbol (or any to_s responder).

  # Examples
  #
  #   in your layout application.html.erb: 
  #
  #     <body class="<%= body_classes(yield :body_classes) %>">

  #   in your view, e.g. for users#show:
