 // TODO:
 // 1) Done: Limit to first 1000

 // 3) Work out support for selecting composites and limiting search to those
 // 4) Work out simple verses advanced tabs
 // 5) work out support for non-encode downloads
 // 6) Make an hgTrackSearch to replces hgTracks track search ??   Silpler code, but may not be good idea.
