/**
 * Default object converter. It converts an object to a String using either toString()
 * or the AbstractFormatter specified in the ConverterContex's userObject.
 * <p/>
 * For example,
 * <code><pre>
 *  MaskFormatter mask = null;
 *  try {
 *      mask = new MaskFormatter("###-##-####");
 *  }
 *  catch (ParseException e) {
 *      e.printStackTrace();
 *  }
 *  ConverterContext ssnConverterContext = new ConverterContext("SSN", mask);
 * </pre></code>
 * If so, it will use the MaskFormatter's stringToValue and valueToString methods to do the conversion.
