Method getError
      A method to send the error as reported by the mysql server

Parameters:

Notes:
      This method outputs the error string stored in $this->db_error.
      This member variable is overwritten each time another db error 
      occurs, so this method must be called as soon as an error has occured

Example Usage:
      if($db = new dbMysql("localhost", "user", "pass", "db_name"))
      {
        //Execute some code on succesful connection here.
      }
      else
      {
        //Send the error encountered.      
        echo $db->getError();
      }

 function getError()
  {
    return $this->db_error;    
  }
