Make this library asynchronous

[danielo515]

Hello,

This mocking library seems to be very handy and most confortable to use that other solutions out there. However, to be a real mongo mockup it should be asynchronous, like the real mongo driver. Currently that small detail makes this totally useless.

Please think about it.

Or just implement the missing Promise interface, that will yield asynchronicity by itself using nextTick.
