module ApplicationHelper
  # Public: Add a bunch of default class names to your html body element.
  #         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:
  #
  #     <% content_for :body_classes, %w(slim bright) %>
  #
  #   will output:
  #
  #   <body class="yourapp users show mobile slim bright">
  #
  # Returns a string of class names to be added to your body element
