This policy specifies a group of tools to work with collections.
A collection is a group of media items with a semantic grouping. A list of podcast episodes can be a collection, as is a playlist.
These tools help determine if an IviMediaItem parent item is a collection, and provide actions to follow a media item as a collection. Following a collection needs to be supported by the source, and usually means that the collection is saved to the user profile (e.g. follow a podcast to receive notification of new episodes, like a playlist to have it in the favorites list).
