SparkHtmlReporter : setCSS is not working. #43

Hi,
setCSS is not working. Generated source shows that there is a nested <style> tag as shown below.

sparkHtmlReporter.config().setCSS(".test {display:block;}"); results in below

<style>
        <style type="text/css">
            .test {
                    display:block;
                  }
        </style>
    </style>
