Title: Update README

Scoobi has a `combine` primitive, which works just like your reduce (using hadoop's combine).

And scoobi also has really great support for transparent serialization. There's a bit of information here: https://github.com/NICTA/scoobi/wiki/Serialization (Note: the explicit stuff is very rarely required, it's just used to allow you to provide your own efficient schemes). And the pretty robust object graph serialization happens here: https://github.com/NICTA/scoobi/blob/master/src/main/scala/com/nicta/scoobi/impl/rtt/ClassBuilder.scala (It's actually using reflection to turn object graph into Java code that would completely reproduce it, then compiles it, and sends the byte code down)
