Todo list tutorial

• Every programming language or framework needs to have a todo list example project.
• We will build a small but real application with persistence.
• It will introduce repeated lists, actions, and persistent state.

What we'll build

• Form handling.
• Session-backed state.
• List rendering.
• Small-scale application structure.

Build stages

• Add a form to create items.
• Store items in the session.
• Use application classes to represent the model.
• Render the list from stored data.
• Mark items complete or remove them.

Taking it further

• How could a database be used?
• How could multiple users manage their own todo lists concurrently?

We'll build on the code introduced in the todo list to build a full database-backed application in the address book tutorial. There's also an extension of this tutorial that adds testing from the start in todo list TDD tutorial.
