Preferred Language

This node determines the preferred language from an 'Accept-Language' type string, as it is given by HTTP req.headers.
E.g. something like de-CH;q=0.7,de;q=0.8,en;q=0.5,de-DE;q=0.9,fr;q=0.3.

It is intended to be used for multilingual flows that need to determine the preferred language of the caller, e.g. a web site user. The node expects a list of languages supported by the flow to choose from.
