To highlight all occurrances of "bla" (case insensitive) in all li elements, use the following code:
	$('li').highlight('bla');

Remove highlighting
	The highlight can be removed from any element with the removeHighlight function.
	In this example, all highlights under the element with the ID highlight-plugin are removed.

	$('#highlight-plugin').removeHighlight();
