Wants and answers:
- Wants and answers are both coded as bit patterns: first item shown is 1, next is 10, etc.
- For wants, interface gives a check box for each item.
When a level is checked, the interface fills all the above levels also.
When a level is unchecked, and there are checked levels above it, all levels below are unchecked.
- Only one answer is possible, so interface gives radio buttons for the items.
