Aimed at touchscreens but can be used for any purpose where the user is required to follow hyperlinks between tracks
Profiles for media tracks (message, image, video, audio ) specify links to other tracks

The show begins at first-track and then uses events (GPIO, keypresses etc.) to link to other tracks via their symbolic names
If using 'call' keeps a record of the tracks it has visited so the 'return' command can go back.
Executes timeout-track if no user input is received.
links are of the form:
symbolic-name command [track-ref]
link commands:
call <track-ref> play track-ref and add it to the path
return - return 1 back up the path removing the track from the path, stops at home-track.
return n - return n tracks back up the path removing the track from the path, stops at home-track.
return <track-ref> return to <track-ref> removing tracks from the path
home - return to home-track removing tracks from the path
jump <track-ref-> - play trck-ref forgetting the path back to home-track
goto <track-ref> - play track-ref, forget the path
exit - end the hyperlink show
null - inhibits the link defined in the show with the same symbolic name.
