Subject: [PATCH] Update README.md

It is important to let people know that there is also Request argument passed.
Also, in some cases, it is very important to have associative array and determining keys in callback.
Please amend to address them. I have added also example.

also, please make a small addition in readme, to describe what is "group" class in the repo, as i found no usage examples.
Thanks for nice work.
