 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
