 Goal: A stand-alone efficient library to do learning via boosting in functional space
 
+Existing interesting features:
+(1) Sparse feature format, handling of missing features. This allows efficient categorical feature encoding as indicators. The speed of booster only depens on number of existing features.
+(2) Layout of gradient boosting algorithm to support generic tasks, see project wiki.
