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".
xval: Retrieve the cross-validation GINI Coefficcient
