* Columns are a problem.
* Really there is no perfect solution to columns at the moment.
*
* - Using Tables is problematic semanticly.
* - Using inline or float to create columns, causes the answers
* flows horizontally, not vertically which is not ideal visually.
* - Using CSS3 columns is also a problem because of browser support
* and also because if you have answeres split across two or more
* lines, and those answeres happen to fall at the bottom of a
* column, the answer might be split across columns as well as
* lines.
* - Using nested unordered list with the first level of <LI>s
* floated is the same as using tables and so is bad semantically
* for the same reason tables are bad.
* - Breaking the unordered lists into consecutive floated unordered
* lists is not great semantically but probably not as bad as
* using tables.
*
* Because I haven't been able to decide which option is the least
* bad, I have handed over that responsibility to the admin who sets
* LimeSurvey up on their server.
*
* There are four options:
* 'css' using one of the various CSS only methods for
* rendering columns.
* (Check the CSS file for your chosen template to see
* how columns are defined.)
* 'ul' using multiple floated unordered lists. (DEFAULT)
* 'table' using conventional tables based layout.
* NULL blocks the use of columns
*
* 'ul' is the default because it's the best possible compromise
* between semantic markup and visual layout.
