Add API method
LGBM_BoosterPredictForMatswhich runs prediction on a data set given as of array of pointers to rows (as opposed to existing methodLGBM_BoosterPredictForMatwhich requires data given as contiguous array).This is added to allow evaluation on training and validation data sets without reformatting of data in LightGBM.Net (C# wrapper).
Also, added a link to LightGBM.NET C# wrapper.
