text: Title: [ASK] New Python recommender systems library - LibRecommender 
  Body: Hi!
  
  just FYI, a new Python library that includes some interesting reco algorithms was recently added to Github: https://github.com/massquantity/LibRecommender
  
  Maybe it would be interesting to include some usecases for some of the included algos that are not covered yet by this repo.
  
  thank you!
