JavaScript HtmlBuilder class
Author: Alessandro Lacava http://www.alessandrolacava.com
Created: Jul 25th, 2006.
Description: This class is responsible to build the HTML code to use within the ticker.
The code is built by parsing the JSON string. Basically,
this is the only code you need to change if you mean
to display the news in some other way. This class is meant to be used in 
conjunction with the ContentRetriever class that is defined inside 
the contentRetriever.js file.
