Drag and drop: To Do List

[clintonjosephs]

Hello 😄 ,

I succeeded in making changes to the To-do-list app, the user is now able to reorder the list by dragging each item and moving it into the desired position.

• Added a class that contains methods related to drag / drop and sorting functionality.
• Add event listeners to list items (dragstart, dragover, drop).
• Update items object's values for index key upon user actions.
