Retrieve the GINI Coefficcient
Retrieves the GINI coefficient from an H2OBinomialMetrics. If "train", "valid", and "xval" parameters are FALSE (default), then the training GINIvalue is returned. If more than one parameter is set to TRUE, then a named vector of GINIs are returned, where the names are "train", "valid" or "xval".

h2o.auc for AUC, h2o.giniCoef for the
GINI coefficient, and h2o.metric for the various
threshold metrics. See h2o.performance for creating
H2OModelMetrics objects.
