It looks like it has been removed from the engine. I just looked at a recent code drop. I'm not sure why they've removed it; but, if it's important to your project I would suggest re-implementing it.
It derives from camera, which appears to be intact in the newer versions of the engine. I wish I could help more specifically, but our version of the engine is older and heavily modified and I don't directly deal with camera animations :)
But, you're not crazy, it was removed.
From what I've seen, it's just a method of playing CameraAnims. As such, moving over the functionality shouldn't be too difficult.
Good luck!
