    Does the list grown indefinitely?
    Or is it pruned somewhere?

> Currently PrequentialEvaluation task supports dumpFile option.  With this 
> option model performance can be saved to a file. However, in some cases it 
> would be good to save also individual predictions made by a model.  This is 
> useful for model debugging and method development.
> This could be also used to visualize model output, calculate custom 
> performance indicators (e.g. model accuracy for instances of a certain class 
> or sharing the same feature value).  Such saving of model output (if done) 
> should be made for every instance. Hence, a new option making it possible to 
> dump predictions to a separate file seems justified.  For classification, it 
> should include votes made for individual classes, if available.
