+ 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
