	=head2 Normal Usage

	Normal usage of the iterator object is to do the following:

	my $it = $navmap->getIterator([your params here]);
	my $curRes;
	while ($curRes = $it->next()) {
	[your logic here]
	}

	Note that inside of the loop, it's frequently useful to check if
	"$curRes" is a reference or not with the reference function; only
	resource objects will be references, and any non-references will
	be the tokens described above.

	Also note there is some old code floating around that trys to track
	the depth of the iterator to see when it's done; do not copy that
	code. It is difficult to get right and harder to understand then
	this. They should be migrated to this new style.

	B<Simple Status>

	Convenience method B<simpleStatus> provides a "simple status" for the resource.
	"Simple status" corresponds to "which icon is shown on the
	Navmaps". There are six "simple" statuses:

	=over 4

	=item * B<CLOSED>: The problem is currently closed. (No icon shown.)

	=item * B<OPEN>: The problem is open and unattempted.

	=item * B<CORRECT>: The problem is correct for any reason.

	=item * B<INCORRECT>: The problem is incorrect and can still be
	completed successfully.

	=item * B<ATTEMPTED>: The problem has been attempted, but the student
	does not know if they are correct. (The ellipsis icon.)

	=item * B<ERROR>: There is an error retrieving information about this
	problem.
