Add recursive boolean option to update

[rjmoggach]

I have a nested dictionary that i'd like updated to be empty when I update with a user config. Ideally the top level attribute would be set to {} and then base_cfg.update(user_cfg, recursive=False) would nuke the whole dict with the user value of {}

[rjmoggach]

for now i'm doing the following:

                for k,v in user_cfg.items():
                    if k in base_cfg and base_cfg[k] != v:
                        base_cfg.set(k,v)

I'm not entirely sure if I understand what you want to do.

Could you give me two configuration examples (e.g. two YAML files) which show the current behavior vs the one you would like to get?
