!ToDoList commentStamp: '<historical>' prior: 0!
ToDoList holds tasks to do by this user.  

This is a model part of this example MVC. In Aida every object can have its Url. Urls therefore point to domain model objects and not to the Apps as their web presentations. Urls are generated automatically when some web link pointed to some domain object. That is, you never need to deal with an Url directly, in in pure OO fashion you deal just with object references. But you can express an Url preference by implementing an #preferedUrl method in your domain class. In our ToDoList case it recommends an nice looking Url like '/name surname/todo'

Instance Variables
	owner	<WebUser>	user as an owner of that todo list
	tasks	<Collection> user's tasks to do
	other	<Dictionary>	 other stuff


!

!ToDoListApp commentStamp: '<historical>' prior: 0!
ToDoListApp is a presentation class for todo list of logged-in user. 

In a pure MVC fashion it servers as a web presenentation (view and controler/actions) of a model object, in our case an instance of ToDoList. Such App have  view methods and action methods or blocks. In our case just #viewMain and no action methods, but we have many action blocks, like #onClickDo: .
!

!ToDoLoginWidget commentStamp: '<historical>' prior: 0!
ToDoLoginWidget for a login popup with ajaxified fields to validate username and password entries immediatelly. 

Note that the login button is nonactive/grayed out until a form is complete and valid, that is, until username and password are entered and correct. 
!

!ToDoRedirectApp commentStamp: '<historical>' prior: 0!
ToDoRedirectApp just redirects to the currently logged-in user's todo list. 

This is a so called standalone App and it is registered at Url '/todo' It is registeredy automatically at install by evaluating:

	AIDASite default register: ToDoRedirectApp onUrl: '/todo'

The whole installation procedure resides on the class initializing methods .
!

!ToDoTask commentStamp: '<historical>' prior: 0!
ToDoTask describes a task to be completed.

Instance Variables
	id	<String> task number to uniquely identify a task
	name	<String>	 short name of the task
	description	<String>	description of description
	deadline	<Date>	when this task should be completed
	members	<Set>	additional users assigned to this task
	status	<Symbol>	#pending or #complete
	parent	<ToDoList>	a todo list where this task belongs
!

!ToDoTaskWidget commentStamp: '<historical>' prior: 0!
ToDoTaskWidget for adding new task or editing existing one. It also provides a popup to manage a "membership", that is, additional users assigned to that task.

Widget in Aida is a standalone reusable component, with its own class. It alos have its own form. But every web element (as instance of WebElement) is is standalone and reusable too (also Ajax updatable). Difference between web elements and widgets is only that former are created in methods in Apps and widget, while later has their own classes. and widgets have again methods to create web elements... 

Instance Variables
	mode	<Symbol>     #add or #edit
	task 	<ToDoTask> which task is edited
