The appveyor fail is really strange, I wonder if it is due to the testing using Windows, since on Linux I can't replicate it. |

Modified predict so that the representations are computed only once for each user and item.
The same idea could be applied on predict_rank (I wanted to get your opinion first though).
I also added a method predict _score that accepts the same input as predict_rank, but is based on predict by unrolling the matrix as an array.
