    Abstract base class for model visitors.

    This class defines the interface for visiting a model generator. 
    Subclasses must implement the visit method to define 
    specific behaviors for different types of model generators.

    Methods:
        visit(generator, *args, **kwargs):
            Abstract method to visit the model generator. Subclasses 
            must override this method to provide specific functionality.

    Example:
        class IbmTextGenerator(ModelVisitor):
            def visit(self, model_generator, *args, **kwargs):
                # Implement specific behavior here
                pass
