Description

Depends on extend-instance http://dev.clojure.org/jira/browse/CLJS-398

First patch backs atoms by a protocol IPlace and implements reset! and swap! and compare-and-set! only with protocols

Second patch uses extend-instance to implement global-hierarchy a custom lazy atom

In effect, multimethods and hierarchies can be omitted by gclosure, taking 1K off of hello world

The protocol should probably just be called IAtom. A note, changing atoms to go through protocols has performance implications - generally protocol fns are about twice as slow as regular fns.

I'll take a closer look.
