* relation to xgboost.h:
* (1) xgboost.h provides a interface to a single booster(e.g. a single regression tree )
* while GBMBaseModel builds upon IBooster to build a class that
* ensembls the boosters together;
* (2) GBMBaseModel provides prediction buffering scheme to speedup training;
* (3) Summary: GBMBaseModel is a standard wrapper for boosting ensembles;
