Reference implementation of score construction

[lucivpav]

InLoc_demo assumes score array at the input. The score array determines the similarity between query-cutout pairs. The scores are presumably computed by first computing features of the query/cutout images and computing their dot product.

I have provided an implementation of how the input scores are built. However, it would be nice to include it also in this repository for reference. If you agree with my implementation, feel free to copy any of my code and use it in this repository.

Best regards,
