    A class for executing tasks with a fallback mechanism in case of errors.
    
    This class attempts to execute a given function. If an exception occurs,

        task_function (Callable): The main function to attempt execution on.
        fallback_function (Callable): The function to use as a fallback if the
            `task_function` raises an exception.
    
    Methods:
        execute: Attempts to run the provided `task_function`, and if it fails,
                 runs the `fallback_function`.
