# Includes +url_for+ into the host class. The class has to provide a +RouteSet+ by implementing
# the <tt>_routes</tt> method. Otherwise, an exception will be raised.
#
# In addition to <tt>AbstractController::UrlFor</tt>, this module accesses the HTTP layer to define
# url options like the +host+. In order to do so, this module requires the host class
# to implement +env+ and +request+, which need to be a Rack-compatible.
#
# Example:
#
# class RootUrl
# include ActionController::UrlFor
# include Rails.application.routes.url_helpers
#
# delegate :env, :request, :to => :controller
#
# def initialize(controller)
# @controller = controller
# @url = root_path # named route from the application.
# end
# end
# =>
