    A class for executing functions with a fallback mechanism in case of errors.
    
    Args:
        primary_function: The main function to be executed.
        fallback_function: The function to be used as a fallback if the primary function fails.
        error_types: Tuple of exception types that should trigger the fallback. Default is (Exception,).
        
    Example Usage:
        >>> def divide(a: float, b: float) -> float:
        ...     return a / b
        ...
        >>> def safe_divide(a: float, b: float) -> Optional[float]:
