28 * This box provides a reference from the containing track to another track in the presentation. These references
29 * are typed. A 'hint' reference links from the containing hint track to the media data that it hints. A content
30 * description reference 'cdsc' links a descriptive or metadata track to the content which it describes.
31 * Exactly one Track Reference Box can be contained within the Track Box.
32 * If this box is not present, the track is not referencing any other track in any way. The reference array is sized
33 * to fill the reference type box.
