/**
* Defines a source, playlist or track.
*
* An ITObject uniquely identifies a source, playlist, or track in iTunes using
* four separate IDs. These are runtime IDs, they are only valid while the
* current instance of iTunes is running.
*
* As of iTunes 7.7, you can also identify an ITObject using a 64-bit persistent
* ID, which is valid across multiple invocations of iTunes.
*
* The main use of the ITObject interface is to allow clients to track iTunes
* database changes using
* <code>iTunesEventsInterface.onDatabaseChangedEvent()</code>.
*
* You can retrieve an ITObject with a specified runtime ID using
* <code>iTunes.getITObjectByID()</code>.
*
* An ITObject will always have a valid, non-zero source ID.
*
* An ITObject corresponding to a playlist or track will always have a valid
* playlist ID. The playlist ID will be zero for a source.
*
* An ITObject corresponding to a track will always have a valid track and
* track database ID. These IDs will be zero for a source or playlist.
*
* A track ID is unique within the track's playlist. A track database ID is
* unique across all playlists. For example, if the same music file is in two
* different playlists, each of the tracks could have different track IDs, but
* they will have the same track database ID.
*
* An ITObject also has a 64-bit persistent ID which can be used to identify
* the ITObject across multiple invocations of iTunes.
