class FallbackExecutor:
    """
    A class that provides a fallback mechanism for executing functions,
    allowing limited error recovery in case an exception occurs during execution.

    :param primary_func: The main function to execute.
    :type primary_func: callable
    :param fallback_func: The function to execute if the primary function raises an exception.
    :type fallback_func: callable or None
    :raises ValueError: If both `primary_func` and `fallback_func` are not callable.

    Example usage:
        >>> def divide(a, b):
        ...     return a / b
        ...
        >>> def log_error(e):
        ...     print(f"Error occurred: {e}")
