    A class that provides a fallback mechanism for executing functions in case of errors.

    Usage:
        >>> def func_a() -> str: return "Result A"
        >>> def func_b() -> int: return 123
        >>> executor = FallbackExecutor(func_a, func_b)
        >>> print(executor.execute("func_a"))  # Result: 'Result A'
        >>> print(executor.execute("func_c", fallback=func_b))  # Result: 123

    Args:
        *functions (Callable): Variable number of functions to be executed.
