class FallbackExecutor:
    """
    A class for creating a fallback executor that can be used to handle errors in function calls.

    This class allows defining a main function and an optional fallback function.
    If the main function raises an exception, the fallback function will be executed instead,
    or the error will be raised if no fallback is provided.

    Example usage:
    >>> def divide(x: float, y: float) -> float:
    ...     return x / y
    ...
    >>> def safe_divide(x: float, y: float) -> Optional[float]:
    ...     try:
    ...         return divide(x, y)
    ...     except ZeroDivisionError:
    ...         print("Caught a division by zero. Returning None.")
    ...         return None
    ...
    >>> fallback_executor = FallbackExecutor(safe_divide, fallback_function=None)
    >>> result = fallback_executor.execute(10.0, 2.0)  # Returns 5.0
    >>> result = fallback_executor.execute(10.0, 0.0)  # Prints "Caught a division by zero. Returning None." and returns None
