It might make sense to have an option that the questions be shuffled in a new position with each new page load.
We already have a "shuffle" parameter, but this just adds a shuffle button. I'm honestly not sure what the point of it is :).
Currently shuffle= none removes the shuffle button. We should allow
<quiz display="simple" shufflequestions="true"> </quiz>
To shuffle the questions with each page load.
This param should respect the shuffle control tags.
