Great, this will make the StructDict behavior more consistent.. just one question, how can we make deep copies? The default shallow copies seem quite dangerous from a user perspective?!

[dfsp-spirit]

I have implemented a .deepcopy() method in 9560672.

I have also implemented __deepcopy__, so one can also use:

import copy
my_cfg_cp = copy.deepcopy(my_cfg)

[tensionhead]

Ok great, now ppl can safely throw around .copy() on their cfg's 👍
