      Description

      The RecommenderEvaluator implementation is hard-coded around the standard algorithm for comparing a recommender's performance on training v.s. test datasets.

      This is a rewrite supplying other algorithms, and the ability to directly compare DataModels. It was born out of a desire to check that a new recommender made sense compared to existing recommenders, and to directly work with DataModels that encompass the entire recommendation space.

          Description The RecommenderEvaluator implementation is hard-coded around one algorithm.
          This is a more flexible, modular rewrite.
