We create a kml file with gx:MultiTrack, succeed putting it into cesium and make it move.
Basically we fallow the bike ride example(https://cesiumjs.org/Cesium/Build/Apps/Sandcastle/?src=KML.html&label=DataSources)
But after it finish the tour, it just automatically go back to the first coordinate and start all over again.
How to make it only run once?
