-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
