Repetition Factors

A repetition factor can be placed in brackets before a literal element to have the element repeated. For example, the statement

   answer={[2]  'Yes', [2]  'No'};
is equivalent to
   answer={'Yes' 'Yes', 'No' 'No'};
and results in the matrix
                                ANSWER
                                Yes   Yes
                                No    No
