Representation of quick share link
The shared link id provides a short id that can be part of a short app url that is easy to
copy/paste/send (via email or other).
As of now, these shared links are public in that they provide unauthenticated access to the
node's content and limited metadata info, such as file name and last modifier/modification.
In the future, the QuickShareService *could* be enhanced to provide additional features,
such as link expiry &/or "password" protection, etc.
