# This module defines the delegate_with_credentials method on classes that include it
# This allows the class to say the following :
#
#   delegate_with_request :users, Trumpet::User
# 
# And any instance of the class will have a users method on it, which will delegate
# calls to the Trumpet::User class with the proper request object in the args
