negotiate() public static method

Performs content-type negotiation on a Request object, by iterating over the accepted types in sequence, from most preferred to least, and attempting to match each one against a content type defined by Media::type(), until a match is found. If more than one defined type matches for a given content type, they will be checked in the order they were added (usually, this corresponds to the order they were defined in the application bootstrapping process).
