now any user that solves problems by themselves will have their own problem set updated. before it kept updating user_id = 1 (i believe just for testing)
added in partial for exercise list to load in the modal during a session. changed the layout so that we have a better styled toolbar at the top. and am working on getting everything fixed in terms of layout in the modal.
got the modal to look as it did before, but a little bit cleaner. next need to have the exercises scroll but keep the right column fixed
cleaned up layout, took out prettyprint() command and problem and overview started showing up
