@ariv3ra

@ryansb already crafted a patch here (#41) but it needs some more polishing before merging into master (review interface and make some tests). I won't be able to look at this at least until the next week, so If you want to go through the code and give us your opinion and make the changes so it can be merged it'd be great!.

I can iterate when either of you have a chance to look over my PR.

@warik @MeGaPk there's a first approach in #41. If you need this functionality we encourage you to add the corresponding tests to the current PR and contribute to Goreq so we can all make it a better library
