GenericUserPreferenceArray Class

NReco.Recommender Class Library

Like GenericItemPreferenceArray but stores preferences for one user (all user IDs the same) rather than one item.

This implementation maintains two parallel arrays, of item IDs and values. The idea is to save allocating IPreference objects themselves. This saves the overhead of IPreference objects but also duplicating the user ID value.
