In Wave 02 we will update the Task List Front End to store state in the App.

Lifting up state will set us up to connect our front end to our back end API.

We will update and implement the following features:

1. Update the toggle complete feature of each Task to update the state of the task data stored in App.
2. Add a feature to delete a task from the task data stored and rendered by the App.
