/**
* The ScormQuestion class is a gateway to getting the answers exported
* (the question is just an HTML text, while the answers are the most important).
* It is important to note that the SCORM export process is done in two parts.
* First, the HTML part (which is the presentation), and second the JavaScript
* part (the process).
* The two bits are separate to allow for a one-big-javascript and a one-big-html
* files to be built. Each export function thus returns an array of HTML+JS.
