Trait allowing models to prepare additional info for nodes (e.g. links, sample data etc.)
Implementations have to be registered via ServiceLoader mechanism.
additionalInfo method is invoked when node changes, so it should be relatively fast.
TODO: this trait should be in API, but we rely on NodeData, so we have to have it in interpreter ATM...
