    A class that implements a fallback execution strategy for functions.
    
    This class provides a mechanism where if a primary function call fails,
    it can try alternative methods or revert to default behavior.

    Args:
        primary_function (Callable): The main function to be executed.
        backup_functions (List[Callable]): List of functions to attempt as backups in case the primary function fails.
        error_threshold (int, optional): Maximum number of retries before giving up. Defaults to 3.
    
    Attributes:
        primary_function (Callable): The user-defined main function.
        backup_functions (List[Callable]): A list of fallback functions.
        error_count (int): Number of failed attempts.

    Raises:
        Exception: If no backups are available or all backups fail after retries.
