Would be nice to trigger node selection reset on update

empress/empress/support_files/js/selection-callback.js

Lines 23 to 33 in 36df44c

	// 3 seconds before resetting
	setTimeout(function () {
	empress.resetTree();
	empress.drawTree();
	samples.forEach(function (sample) {
	sample.material.emissive.set(0x000000);
	});
	plotView.needsUpdate = true;
	}, 4000);

It would be nice to reset this when the user updates either the emperor plot or the empress tree. That way the user can explore the tree after they select nodes in emperor.
