> Support nodejs multilang protocol.
> Design considerations:
> - Emit will receive an object (like args and kwargs in python) and a callback that is called when task ids list is received.
>             self.emit({tuple: [word]}, function(taskIds) {
>                 self.log(word + ' sent to task ids - ' + taskIds);
>             });
> - The following methods will received done method that must be invoked on completion (same pattern used by the mocha test framework for async unit tests). 
> - Internal implementation of emit uses Process.stdout.write without a callback since nodejs streams maintain FIFO order (so far, we have not found a need for providing a callback).
