873:
874: Randomizes the list of foils.
875: Respects
876: - each foils desire to be randomized
877: - the existance of Concept groups of foils (select 1 foil from each)
878: - and selects a single correct statement from all possilble true statments
879: - and limits it to a toal of $max foils
880:
881: WARNING: this routine uses the random number generator, it should only
882: be called once per target, otherwise it can cause randomness changes in
883: homework problems.
884:
885: Arguments
886: $max - maximum number of foils to select (including the true one)
887: (so a max of 5 is: 1 true, 4 false)
888:
889: $randomize - whether to randomize the listing of foils, by default
890: will randomize, only if randomize is 'no' will it not
891:
892: Returns
893: $answer - location in the array of the correct answer
894: @foils - array of foil names in to display order
