   Installation:
   1. Put the following snippet into head tags:
      <script type="text/javascript">var tNews=new Array();</script> 
    
   2. Define some tickertexts:
      tNews.push('<a target="_self" href="home_en/press"><b>Lorem ipsum dolor sit amet, consetetur  sadipscing elitr</b><\/a>');
      tNews.push('<a target="_self" href="home_en/expertise"><b>At vero eos et accusam et justo duo dolores et ea rebum.</b><\/a>');
   
   3. Start ticker at desired postion with:
      <script language="javascript" src="/styles/js/horizontalTicker.js"></script>
   
   4. Adjust variables below...
