[Dev] Expand button #8
Description
The expand button in the Dev branch for Records.html, when clicked, should cause all the other students to disappear, and rows under the selected student's row should populate with session info saved. When Collapse is clicked, everything should go back to normal. This will require re-drawing the entire table each time a button is clicked.
I am currently working on this in the dev branch, but don't mind the assistance, so feel free to work on it too as long as I'm not currently pushing commits!
