In some cases it might be nice to put answers into columns
- style applied to answers, for example on this quiz it would be interesting to have long list of short options displayed on several columns
- Add "div class = 'answers'" to wrap the answers, so they can be styled individual of the question text.
- possible add a an additional quiz parameter to set it, like gallery's perrow: https://www.mediawiki.org/wiki/Help:Images
