/*
    FAQ v1.1 Plugin
    
    A dynamic FAQ builder using the power of jQuery.

	Updated December 3rd, 2008 
		- Changed the span to a div - Symantically correct
		- Added an incrementor in case of a duplicate header name
		- Changed the regular expression to anything other than alphanumeric
		- Corrected the syntax to accept the faqHeader variable

    Example HTML Syntax:
    --------------------
    <div id="faq">
        <h2>Title 1</h2>
        <div>Some content</div>
        <h2>Title 2</h2>
        <div>Some content</div>
    </div>

    Example Script Syntax:
    --------------------
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"></script>
    <script type="text/javascript" src="jquery.faq.js"></script>    
	<script type="text/javascript" >
	    $().ready(function() {
			$('#faq').makeFAQ({
				indexTitle: "My Index",
				displayIndex: true,
				faqHeader: "h2"
			});
	    });
	</script>
