* string is an array of $ia arrays.

* $ia[1] => fieldname
* $ia[2] => title
* $ia[3] => question text

* $ia[5] => group id
* $ia[6] => mandatory Y || N
* $ia[7] => conditions exist for this question
* $ia[8] => other questions have conditions which rely on this question (including array_filter and array_filter_exclude attributes)
* $ia[9] => incremental question count (used by {QUESTION_NUMBER})
*
* $conditions element structure

* The point of these functions (setman) is to return an array containing two arrays.
* The first ($mandatorys) is an array containing question, so they can all be checked
* The second ($mandatoryfns) is an arry containing the fieldnames of every question
* What's the difference? The difference arises from multiple option questions, and came
* about when trying to distinguish between answering just one option (which satisfies
* the mandatory requirement, and answering them all). The "mandatorys" input contains the
* actual specific response items that could be filled in.. ie: in a multiple option
* question, there will be a unique one for every possible answer. The "mandatoryfns" array
* contains the generic question fieldname for the question as a whole (it will be repeated
* for multiple option qeustions, but won't contain unique items.
