How to revolve camera slowly around a trackedEntity?

Apologies for what might be a basic question. I've searched through the Sandcastle examples etc and have come up emptyhanded.

I'm trying to have cesium slowly rotate the camera view around a trackedEntity (or any point for that matter). Could someone point me in the right direction?

Basically, you should do a lookAt() at each clock tick and adjust the heading with the time that has passed.
