* Collapsed Topics Information
*
* A topic based format that solves the issue of the 'Scroll of Death' when a course has many topics. All topics
* except zero have a toggle that displays that topic. One or more topics can be displayed at any given time.
* Toggles are persistent on a per browser session per course basis but can be made to persist longer by a small
* code change. Full installation instructions, code adaptions and credits are included in the 'Readme.txt' file.
