	* All known Browsers can display this without problems, but spam harvest robots looking for "@"
	* will stay unsuccessful. Whereas this class can not guarantee 100% protection, it provides 
	* a good solution with no disantvantages for the reader, no Javascript is needed and the mailto:
	* is operational as well as copy/paste within the browser
	* Optional link text can be given, CSS class and Parameters for the Mailto: link
	* such as subject or mail text as associative array ("subject"=>"Mail from my website", "body"=>"Hi! I am sending You this email because I'm bored")
	* Since the object overhead for only one function is unnecessary, You can just use the mailto_encode method
	* as a standalone function

  * @param String [$sText] link text (optional)
  * @param String [$sClass] CSS class (optional)
