Detailed Description

This class prints a view of the question bank, including + Some controls to allow users to to select what is displayed. + A list of questions as a table. + Further controls to do things with the questions.

This class gives a basic view, and provides plenty of hooks where subclasses can override parts of the display.

The list of questions presented as a table is generated by creating a list of question_bank_column objects, one for each 'column' to be displayed. These manage + outputting the contents of that column, given a $question object, but also + generating the right fragments of SQL to ensure the necessary data is present, and sorted in the right order. + outputting table headers.
