    A class designed to handle function execution with fallback mechanisms in case of errors.
    
    Attributes:
        primary_function (Callable): The main function to be executed.
        secondary_functions (List[Callable]): A list of functions that act as fallbacks if the primary function fails.
        error_handler (Callable, optional): An optional handler for custom error management. Defaults to None.
        
    Methods:
        execute: Executes the primary function and falls back to a secondary function in case of an exception.
