Timer App

Please create an app for managing timed tasks.

1. The user can input a text and click Add
2. A new task is added with the title, and 00:00 time, and a play button.
3. Clicking Play will play this task: the timer will start running, and the icon will change to a pause icon. Also - any other running task will be paused.
4. Clicking Pause will pause the task.
5. The total time is always updated.
