Added a small example (3 lines) to illustrate an async function call.
In the hind sight, the guide explains that part pretty well, but there was a bit of confusion in my head and it didn't "click" until I experimented with the async for a bit.
Having an example should help others comprehend the meaning of the paragraph just above it.
I admit that I may be adding more confusion without explaining that
async_func_1_ret_number()returns a number, e.g.200.Happy to expand, but I tried to keep the change to a minimum.
Feel free to reject :)
