In this exam project, you have to implement a todo list site.

You should have such models:

1. Task - todo list is consist of tasks. Each task should have fields for:
   • content - describes what you should do.
   • datetime, when a task was created
   • optional deadline datetime if a task should be done until some datetime
   • the boolean field that marks if the task is done or not
   • tags that are relevant for this task
2. Tag - a tag symbolizes the theme of the task and consists only of a name.

A task can have multiple tags and a tag can be in multiple tasks.

Create the home page. The home page is accessed by 127.0.0.1:8000/, where you should have:

1. Sidebar with the links to:
   • Home page
   • Tag list page the sidebar should be on all pages.
2. Todo list which is a list of tasks.
   • Tasks should be ordered from not done to done and from newest to oldest
   • All task information should be displayed.
   • There should be a button to add a new task.
   • For each task add links for updating and deletion.
   • Also, add a button Complete if a task is not done and Undo if a task is done, this button changes the status of the task to the opposite and redirects to this page.

The home page should look like this:

1. Table with tags names, links for updating, and deletion.
2. Button to add a new tag.
