public interface ScoreAssociation<Desc>

Scores the fit quality between two feature descriptions. A lower score always indicate a better match a larger one. Thus scoreA < scoreB will return true if scoreA is a better score than scoreB. The range of possible scores is not specified by this interface. For example, correlation based scores can take on both positive and negative values while Euclidean will always be positive or zero. NOTES: To ensure that lower is better, correlation scores undergo a sign flip.
