```
    A heroically forgiving message string formatter.
    This method attempts to safely toString all of the args and replaces any "{}" characters with "%s" before formatting via String.format(String, Object[]).
    Any Throwables in the args list will have their short cause string appended to the end of the formatted message.
    If the format is invalid or contains too few or too many args, the method will make sure that all arg toStrings are in the output.
    The goal here is to make sure that no matter what happens, you will get something useful out of this message if not exactly to the format spec.
    
    Parameters:
    
    format - a string containing "{}" arg placeholders of formatted per java.util.Formatter
    
    args - objects that will be replaced into their format placeholders.
    
    Returns:
    
    the formatted string
