React to_do list lab
React to-do list with promote/demote buttons. Make a to-do list from React. It should
have a parent component with functions that are used by the child components -- like the example presented this week.
Each to-do item
should be a able to be 1) removed, 2) edited and saved, 3) promoted -- exchanged with the item
before it, 4) demoted -- exchanged with the item after it.
Each to-do item should have a description and a status. When editing the description
should turn into an input of the text type, and that status should turn into a drop-down
select that allows the user to specify "started" or "not started".
