IMAContentPlayhead
@protocolIMAContentPlayhead
Defines an interface for a class that tracks video content progress and
exposes a key value observable property |currentTime|.
The SDK provides an implementation for tracking AVPlayer-based playback
in the IMAAVPlayerContentPlayhead.
Publishers can supply their own implementation by implementing this
interface and this way support any other video playback implementation
they might have.
