Represents a single result row from a {@link IBookQuery}. In effect, this is a light-wieght, serializable, read-only version of an {@link IBook}bean, plus it contains the owner and holder name (which means we don't have to go find the correct {@link IPerson} to dig out the name).
This is provided for efficient access when doing various queries.
