News ticker plugin (BBC news style)
Bryan Gullan,2007
version 1.1.1
http://www.makemineatriple.com/jquery
Use and distrubute freely with this header

Options (defaults shown):
newsList: "#news" 	// assumes unordered list; specify the ul holding the news items
tickerRate: 80 		// time gap between display of each letter (ms)
startDelay: 100 	// delay before first run of the ticker (ms)
loopDelay: 3000 	// time for which full text of each item is shown at end of print-out (ms)
placeHolder1: " |"	// character placeholder shown on even loops
placeHolder2: "_"	// character placeholder shown on odd loops

Sample usage:
$(document).ready(function() {
	var options = {
  		newsList: "#news",
 		startDelay: 10,
 		placeHolder1: " []"
	}
	$().newsTicker(options);
});

for markup as follows:

<ul id="news">
<li><a href="http://www.makemineatriple.com">MakeMineATriple.com</a></li>
<li><a href="http://www.jquery.com">jQuery</a></li>
</ul>

Underline text decoration on the link is not recommended! :-)
