Add documentation comments to this interface and all methods bellow.

[daniela-webrtc, 2017/03/26 18:08:58]

Remove the <AVCaptureVideoDataOutputSampleBufferDelegate> from the header into a
class extension in the implementation file. It's implementation detail not
needed in the header

Done.

Not sure if the capture session needs to be exposed with the new design. Is it
gonna be used somewhere?

[magjed_webrtc, 2017/03/27 13:11:48]

It's used for RTCCameraPreviewView.m. I guess it's an optimization since we
could use RTCEAGLVideoView instead and not expose this.

[sakal, 2017/03/29 11:45:44]

Yes, this is the reason it exists here.
