Trying out Google V8

Jeena pointed out today that Google V8 may be a good alternative to SpiderMonkey, and it indeed seems so. In short, here is how we can implement callbacks in JS->Erl using erlv8

	-module(v8test).
	-export([run/0]).
	-include_lib("erlv8/include/erlv8.hrl").
	run() ->
	application:start(erlv8),
	{ok, VM} = erlv8_vm:start(),
	Global = erlv8_vm:global(VM),
	Global:set_value("callback", erlv8_object:new([{"exec", fun (#erlv8_fun_invocation{}, []) -> myCallback() end}])),
	erlv8_vm:run(VM,"callback.exec();").
	myCallback() ->
	io:format("Hello from myCallback!~n", []),
	ok.

I have forked the repo Jeena hosts on GitHub to one I host, while playing with V8.
