code: public void addParam(String strParam, String strValue)
      {
          if (strValue == null)
              strValue = NULL;
          m_properties.setProperty(strParam, strValue);
      }
docs: Add this method param to the param list.
  (By default, uses the property method... override this to use an app specific method).
  NOTE: The param name DOES NOT need to be saved, as params are always added and retrieved in order.
  @param strParam The param name.
  @param strValue The param value.
