+
+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
