   Apache::radiobuttonresponse

   Randomizes the list of foils.
   Respects
     - each foils desire to be randomized
     - the existance of Concept groups of foils (select 1 foil from each)
     - and selects a single correct statement from all possilble true statments
     - and limits it to a toal of $max foils
   
   WARNING: this routine uses the random number generator, it should only
   be called once per target, otherwise it can cause randomness changes in
   homework problems.
   
   Arguments
     $max - maximum number of foils to select (including the true one)
            (so a max of 5 is: 1 true, 4 false)
   
     $randomize - whether to randomize the listing of foils, by default
                  will randomize, only if randomize is 'no' will it not
   
   Returns
     $answer - location in the array of the correct answer
     @foils  - array of foil names in to display order
