RTCTrackEvent: RTCTrackEvent() constructor
The RTCTrackEvent() constructor creates and returns a new RTCTrackEvent object,
configured to describe the track which has been added to the RTCPeerConnection.
In general, you won't need to use this constructor, as RTCTrackEvent
objects are created by WebRTC and delivered to your RTCPeerConnector's
ontrack event handler as appropriate.
