-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.

-  $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
