> If a model is trained with mlp regression and then the input table is dropped, mlp predict fails for that model.
> Ideally the predict function should not depend on the existence of the training data. 
> The predict code for regression only needs to know if the dependent varname type is an array or not. This information can be potentially stored in the model's summary table.
> We also need to make sure that the predict function is backwards compatible.
