	Apache::radiobuttonresponse

	=head1 SYNOPSIS

	Handles multiple-choice style responses.

	This is part of the LearningOnline Network with CAPA project
	described at http://www.lon-capa.org.

	=item &whichfoils($max,$randomize)

	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
