class FallbackExecutor:

    A class to handle execution tasks with a fallback mechanism.
    
    This class is designed to execute given functions and recover from potential errors by falling back on predefined alternatives.

    Args:
        primary_function (callable): The primary function to be executed.
        secondary_functions (list[callable], optional): A list of functions to try if the primary function fails. Defaults to an empty list.

    Raises:
        Exception: If no fallback function is available and the primary function fails.

    Returns:
        Any: The result of the successfully executed function or its fallbacks.
