Making MF to be a part of ML.NET (dotnet#1263)
Based on LIBMF, a new matrix factorization module is added into ML.NET. LIBMF is used as a submodule in ML.NET repo and it would be compiled into a Nuget for releasing. Please see LIBMF's official pages (https://www.csie.ntu.edu.tw/~cjlin/libmf/) for mathmatical details.
