    A class for executing a function with fallback mechanisms in case of errors.

    Args:
        func: The primary function to be executed.
        fallback_func: The function to execute if an error occurs in `func`.
        max_attempts: Maximum number of times the function will be attempted before raising an exception.
    
    Returns:
        Any: The result of the successfully executed function or its fallback.

    Raises:
        Exception: If all attempts fail and no valid output can be produced.
