Added some variables to the HTML5 local storage to keep track of which sections of the web page were open during the last visit to the site. This way if a user clicks a link from the schedule section to look at some example code, when they navigate back, the schedule section will still be left open so that the user can immediately click other example code links. This was the only annoyance that I had with the course website this semester, so I wanted to add a fix for it.
