/*
Category on NSDictionary that allows looking up different entries depending
on the preferred language. Only useful if your user data may contain data
tagged with ISO language codes and you want to know which one is the
preferred one. If you've localized your app, you should just use
NSLocalizedString() and specify the different keys in the .strings file
instead.

// These are analogous to the above, but composed keys are not in a dictionary in the entry, but rather are in the containing dictionary with the same key and the language code appended. E.g. "foo.de", "foo.en" etc.
