-def ui_signal(signals:str|list[str]):
-    """
-    Return a decorator for Node classes.
-    @param signals - a list of strings that name the signals to be sent to the UI. 
-    (For convenience, a string gets converted to a list of length 1)
-
-    The decorator performs the following:
-    The class has OUTPUT_NODE set to True.
-    The class UI_OUTPUT is appended (or created) with a comma separated list of these signals
-    The class FUNCTION is wrapped such that the last len(signals) are removed, and added to the
-    ui dictionary using signals as keys.
-
-    So ui_signals(["first","second"]) will wrap a function returning (something, somethingelse, first_signal, second_signal)
-    and will return { "ui": {"first":first_signal, "second":second_signal}, "result":(something, somethingelse) }
