[Obix-framework-tipsandtricks] Deep copy of Configuration

[Aleksi K. <ale...@cs...>]

Hello all,

I have found this piece of code useful (see the end of message). I guess 
achieving this is not possible using imports?

If there is a more direct way of achieving the same result I'd like to 
hear about. If not, something like this could be added to framework...


Best regards,
