    public class Nilad
    extends ExpressionImpl
    This would be an operator that takes no arguments. Niladic user defined functions (no arguments) abount. It is possible to have a niladic operator in QDL, but as of yet there is no basic of one. One possible way would be to use these as control symbols, such a special operator that means to, say, open an editor window. These would also require special handling inthe parser.

        Description copied from interface: ExpressionInterface
        QDL is not strongly typed but Java is, so each node type should have a unique integer and conditionals should use that, not the instanceof operator. This allows for efficient programming with switch statements rather than a bevy of conditionals (potentially each of which gets done even if the correct case has been handled).
