Recommendation library

A simple recommendation library for small projects. The SimpleEngine supports only the "liked" action (i.e. Philip likes the Caprese pizza). The BinatyEngine supports both "liked" and "disliked" actions (i.e. Philip likes the Verdure pizza but dislikes the Arrabbiata pizza)., _(*1)
