Calculate the variable importance of variables in a caretEnsemble.
This function wraps the varImp function in the
caret package to provide a weighted estimate of the importance of
variables in the ensembled models in a caretEnsemble object. Variable
importance for each model is calculated and then averaged by the weight of the overall model
in the ensembled object.
