 * TException class
 *
 * TException is the base class for all PRADO exceptions.
 *
 * TException provides the functionality of translating an error code
 * into a descriptive error message in a language that is preferred
 * by user browser. Additional parameters may be passed together with
 * the error code so that the translated message contains more detailed
 * information.
 *
 * By default, TException looks for a message file by calling
 * {@link getErrorMessageFile()} method, which uses the "message-xx.txt"
 * file located under "System.Exceptions" folder, where "xx" is the
 * code of the user preferred language. If such a file is not found,
 * "message.txt" will be used instead.
