Nested Config

[lmittmann]

Would you be open to a PR that enables nesting inside JSON configurations? This would allow flags containing dots to be looked up at the corresponding path. E.g. the flag a.b could be configured inside {"a": {"b":"xxx"}}.

[peterbourgon]

Probably not.

[lmittmann]

This is possible with fftoml, why not allow it for json and yml?

[peterbourgon]

I think it may have been a mistake to allow it in fftoml.

But, upon reflection, I suspect my initial reaction may be too conservative, and there may be actual value in this feature.

I'm open to reviewing a change that allows nesting of configuration in this way, provided the API and behavior is consistent across ffyaml, fftoml, and ffjson.

Thanks again to both of you!
