Node v8.x N-API asynchronous Promise example addon

Implementation Note

IMPORTANT!

Node.js will process the fulfillment/conclusion of the Promise in an asynchronous fashion (compared to "real-time" in JavaScript) because the fulfillment is added to the event loop's "Promise fulfillment microtask queue", which is processed immediately after the "nextTick microtask queue", even when it is fulfilled synchronously in C++.

If this ever becomes UNTRUE, then you would need to utilize an AsyncWorker (or a similar concept) in order to ensure this Promise is fulfilled asynchronously.
