Simple example how V8 Function\Object Templates can be used

v8-templates-example.cc

// Create a template for the global object and set the built-in global functions
Local<ObjectTemplate> global = ObjectTemplate::New(isolate);
global->Set(
  String::NewFromUtf8(isolate, "log"),
  FunctionTemplate::New(isolate, LogCallback)
);

// Each processor gets its own context so different processors do not affect each other
Persistent<Context> context = Context::New(isolate, NULL, global);
