 * Transform a PHPUnit xml report using XSLT.
 * This transformation generates an html report in either framed or non-framed
 * style. The non-framed style is convenient to have a concise report via mail, 
 * the framed report is much more convenient if you want to browse into 
 * different packages or testcases since it is a Javadoc like report.
