> Today we have a ResultContext which simply has two public variables query and docList. For writing a response, those fields are used to create a DocsStreamer which creates a TransformContext for transformers (which just copies the values like searcher, req, q, etc again).
> It seems the all the methods on TransformContext could be simply moved to ResultContext.
> Only exception is "iterator" needed by ScoreAugmenter, but we could simply pass down the score in the transform() method as well.
> This would result in a ResultContext that could do things like support multiple queries with different return fields, and things like returning a list of docs from another core (think cross-core join).
