Created an entirely new page for logout functionality. Want to ask functionality should be in the user DAO. No error checking yet.
Error checking in log out functionality. I still don't like the else statement, but for now That is all it will say. Changed header.php to redirect you to log in page if you are not logged in in
case people decide to manually type in a URL before logging in. It should only show a blank page saying you are logged in but it currently still populates the styling. Will look into later.
Change userName to username
