48 * This class holds Content objects, and it knows how they should be arranged. At the moment
49 * the ordering is implicit; video content is placed sequentially, and audio content is taken
50 * from the video unless any sound-only files are present. If sound-only files exist, they
51 * are played simultaneously (i.e. they can be split up into multiple files for different channels)
