926:
927: Randomizes the list of foils.
928: Respects
929: - each foils desire to be randomized
930: - the existance of Concept groups of foils (select 1 foil from each)
931: - and selects a single correct statement from all possilble true statments
932: - and limits it to a toal of $max foils
933:
934: WARNING: this routine uses the random number generator, it should only
935: be called once per target, otherwise it can cause randomness changes in
936: homework problems.
937:
938: Arguments
939: $max - maximum number of foils to select (including the true one)
940: (so a max of 5 is: 1 true, 4 false)
941:
942: $randomize - whether to randomize the listing of foils, by default
943: will randomize, only if randomize is 'no' will it not
944:
945: Returns
946: $answer - location in the array of the correct answer
947: @foils - array of foil names in to display order
