+ *
+ * This function negotiates the clients preferred content type based on its
+ * Accept HTTP header.  The qualifier is recognized and content types 
+ * without qualifier are rated highest.
+ * 
+ * Expects an array as parameter cotaining the supported content types as values.
+ * If the optional second parameter is supplied, it will be filled with an
+ * array containing the negotiation results.
+ * 
+ * Returns the negotiated content type or the default content type 
+ * (i.e. first array entry) if none match.
+ * 
+ * Example:
+ * <pre>
+ * <?php
+ * $ctypes = array('application/xhtml+xml', 'text/html');
+ * http_send_content_type(http_negotiate_content_type($ctypes));
+ * ?>
+ * </pre>
