Add ability to replay tracks

[csherman-dstl]

• Add base TrackFeeder class.
• Add ReplayTrackFeeder class to take a set of tracks and re-feed them.

Think it would be good to include metadata as well as the track id.

Could possibly break for loop early on assumption that track should be time ordered?

Could probably make this more efficient as well by maintaining and iterator for each track and only consuming and appending new states...but that's getting bit more complex, and probably something to revisit if performance is an issue.

Suggested change

	track_states = [state for state in track if state.timestamp <= time]
	current_track = output_tracks.get(track, Track())
	current_track.states = track_states
	output_tracks[track] = current_track
	track_states = []
	track_metadatas = []
	for state, metadata in zip(track.states, track.metadatas):
	if state.timestamp <= time:
	track_states.append(state)
	track_metadatas.append(metadata)
	current_track = output_tracks.setdefault(
	track, Track(id=track.id, init_metadata=track.init_metadata))
	current_track.states = track_states
	current_track.metadatas = track_metadatas
