My tello clone:
1.Add New taks to Todo Column by clicking the top button.
2.You can assign tasks to diffrent users and select different color lables for them. User-list hard coded.
3.Click on the card to open and add comment on it.
4.Can tag multiple users in the comment.
5.Drag the cards around to change there status.
Currently local-storage is used to make the data persistent. Can be easily replaced by actual backed api. Need to change only api.js.
