-Description: Functions for creating ensembles of caret models: caretList
-    and caretStack.  caretList is a convenience function for fitting multiple
-    caret::train models to the same dataset. caretStack will make linear or
-    non-linear combinations of these models, using a caret::train model as a
-    meta-model, and caretEnsemble will make a robust linear combination of
-    models using a glm.
