+random forests for survival, competing risks, regression and classification
+based on Ishwaran and Kogalur's popular random survival forests (RSF) package.
+It handles missing data and now includes multivariate, unsupervised forests,
+quantile regression and solutions for class imbalanced data.  It provides a
+fast interface using subsampling and confidence regions for variable
+importance.")
