  class Mapper
    # Includes devise_for method for routes. This method is responsible to
    # generate all needed routes for devise, based on what modules you have
    # defined in your model.
    #
    # ==== Examples
    #
    # Let's say you have an User model configured to use authenticatable,
    # confirmable and recoverable modules. After creating this inside your routes:
    #
    # devise_for :users
    #
    # This method is going to look inside your User model and create the
    # needed routes:
    #
    # # Session routes for Authenticatable (default)
    # new_user_session GET /users/sign_in {:controller=>"devise/sessions", :action=>"new"}
    # user_session POST /users/sign_in {:controller=>"devise/sessions", :action=>"create"}
    # destroy_user_session DELETE /users/sign_out {:controller=>"devise/sessions", :action=>"destroy"}
    #
    # # Password routes for Recoverable, if User model has :recoverable configured
    # new_user_password GET /users/password/new(.:format) {:controller=>"devise/passwords", :action=>"new"}
    # edit_user_password GET /users/password/edit(.:format) {:controller=>"devise/passwords", :action=>"edit"}
    # user_password PUT /users/password(.:format) {:controller=>"devise/passwords", :action=>"update"}
    # POST /users/password(.:format) {:controller=>"devise/passwords", :action=>"create"}
    #
    # # Confirmation routes for Confirmable, if User model has :confirmable configured
    # new_user_confirmation GET /users/confirmation/new(.:format) {:controller=>"devise/confirmations", :action=>"new"}
    # user_confirmation GET /users/confirmation(.:format) {:controller=>"devise/confirmations", :action=>"show"}
    # POST /users/confirmation(.:format) {:controller=>"devise/confirmations", :action=>"create"}
    #
    # ==== Options
    #
    # You can configure your routes with some options:
    #
    # * :class_name => setup a different class to be looked up by devise, if it cannot be
    # properly found by the route name.
    #
    # devise_for :users, :class_name => 'Account'
    #
    # * :path => allows you to setup path name that will be used, as rails routes does.
    # The following route configuration would setup your route as /accounts instead of /users:
    #
    # devise_for :users, :path => 'accounts'
    #
    # * :singular => setup the singular name for the given resource. This is used as the instance variable
    # name in controller, as the name in routes and the scope given to warden.
    #
    # devise_for :users, :singular => :user
    #
    # * :path_names => configure different path names to overwrite defaults :sign_in, :sign_out, :sign_up,
    # :password, :confirmation, :unlock.
    #
    # devise_for :users, :path_names => { :sign_in => 'login', :sign_out => 'logout', :password => 'secret', :confirmation => 'verification' }
    #
    # * :controllers => the controller which should be used. All routes by default points to Devise controllers.
    # However, if you want them to point to custom controller, you should do:
    #
    # devise_for :users, :controllers => { :sessions => "users/sessions" }
    #
    # * :failure_app => a rack app which is invoked whenever there is a failure. Strings representing a given
    # are also allowed as parameter.
    #
    # * :sign_out_via => the HTTP method(s) accepted for the :sign_out action (default: :get),
    # if you wish to restrict this to accept only :post or :delete requests you should do:
    #
    # devise_for :users, :sign_out_via => [ :post, :delete ]
    #
    # You need to make sure that your sign_out controls trigger a request with a matching HTTP method.
    #
    # * :module => the namespace to find controllers (default: "devise", thus
    # accessing devise/sessions, devise/registrations, and so on). If you want
    # to namespace all at once, use module:
    #
    # devise_for :users, :module => "users"
    #
    # Notice that whenever you use namespace in the router DSL, it automatically sets the module.
    # So the following setup:
    #
    # namespace :publisher do
    # devise_for :account
    # end
    #
    # Will use publisher/sessions controller instead of devise/sessions controller. You can revert
    # this by providing the :module option to devise_for.
    #
    # Also pay attention that when you use a namespace it will affect all the helpers and methods for controllers
    # and views. For example, using the above setup you'll end with following methods:
    # current_publisher_account, authenticate_publisher_account!, publisher_account_signed_in, etc.
    #
    # * :skip => tell which controller you want to skip routes from being created:
    #
    # devise_for :users, :skip => :sessions
    #
    # * :only => the opposite of :skip, tell which controllers only to generate routes to:
    #
    # devise_for :users, :only => :sessions
    #
    # * :skip_helpers => skip generating Devise url helpers like new_session_path(@user).
    # This is useful to avoid conflicts with previous routes and is false by default.
    # It accepts true as option, meaning it will skip all the helpers for the controllers
    # given in :skip but it also accepts specific helpers to be skipped:
    #
    # devise_for :users, :skip => [:registrations, :confirmations], :skip_helpers => true
    # devise_for :users, :skip_helpers => [:registrations, :confirmations]
    #
    # * :format => include "(.:format)" in the generated routes? true by default, set to false to disable:
    #
    # devise_for :users, :format => false
    #
    # * :constraints => works the same as Rails' constraints
    #
    # * :defaults => works the same as Rails' defaults
    #
    # ==== Scoping
    #
    # Following Rails 3 routes DSL, you can nest devise_for calls inside a scope:
    #
    # scope "/my" do
    # devise_for :users
    # end
    #
    # However, since Devise uses the request path to retrieve the current user,
    # this has one caveat: If you are using a dynamic segment, like so ...
    #
    # scope ":locale" do
    # devise_for :users
    # end
    #
    # you are required to configure default_url_options in your
    # ApplicationController class, so Devise can pick it:
    #
    # class ApplicationController < ActionController::Base
    # def self.default_url_options
    # { :locale => I18n.locale }
    # end
    # end
    #
    # ==== Adding custom actions to override controllers
    #
    # You can pass a block to devise_for that will add any routes defined in the block to Devise's
    # list of known actions. This is important if you add a custom action to a controller that
    # overrides an out of the box Devise controller.
    # For example:
    #
    # class RegistrationsController < Devise::RegistrationsController
    # def update
    # # do something different here
    # end
    #
    # def deactivate
    # # not a standard action
    # # deactivate code here
    # end
    # end
    #
    # In order to get Devise to recognize the deactivate action, your devise_scope entry should look like this:
    #
    # devise_scope :owner do
    # post "deactivate", :to => "registrations#deactivate", :as => "deactivate_registration"
    # end
    #
