    A class for executing a main function with fallbacks in case of errors.

        primary_function: The main function to be executed.
        fallback_functions: A list of functions that can be used as fallbacks if the primary function fails.
        error_handler: An optional function to handle exceptions. If provided, it will be called before attempting any fallbacks.
        
    Example usage:
    
    def main_function(x: float) -> float:
        return 1 / x
