How to load a level from an Asset Bundle?

I've been using LoadLevel to bring up the main level for my game. I decided to make it into an asset bundle that can be downloaded instead of being included in the build.

That's where I hit a stopping point.

Can someone give me a quick example of code that will load a level from an asset bundle? Everything I've tried has failed in some way.

For the record, I've got other asset bundles loading up and instantiating just fine, but doing it with a whole level is throwing me off.

for example You can refer to StreamAdditiveScene.js
