Your task is to create a todo list application, similar to the applications we built in class.

Your app should have a form that allows the user to type in a new task. It should also have a save button.

Use JavaScript to prevent the form from submitting to the server. Instead, use your DOM manipulation skills to add the task to the page.

Each task that is added to the page should have a done and a delete button. The done button strikes through the todo item, the delete button removes it. If an item is 'done', the done button becomes undo and clicking on it removes the strikethrough.
