module Herbert
  # This class allows you to organize code by REST resources.
	# Any class that subclasses Herbert::Resource is automatically "merged" 
	# into the application. Resource name will be derived from the class name.
	# 
	# For instance,
	#   class Messages < Herbert::Resource
  #     get '/' do
  #    	  "here's a message for you!"
  #     end
	#   end
	# will respond to 
	#   GET /messages/
	#
