867:
868: Randomizes the list of foils.
869: Respects
870: - each foils desire to be randomized
871: - the existance of Concept groups of foils (select 1 foil from each)
872: - and selects a single correct statement from all possilble true statments
873: - and limits it to a toal of $max foils
874:
875: WARNING: this routine uses the random number generator, it should only
876: be called once per target, otherwise it can cause randomness changes in
877: homework problems.
878:
879: Arguments
880: $max - maximum number of foils to select (including the true one)
881: (so a max of 5 is: 1 true, 4 false)
882:
883: $randomize - whether to randomize the listing of foils, by default
884: will randomize, only if randomize is 'no' will it not
885:
886: Returns
887: $answer - location in the array of the correct answer
888: @foils - array of foil names in to display order
