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