[Contrib: Evaluation System] Question about EvalEvaluation properties

[Aaron Zeckoski]

Those both sound fine to me. I added in that field to allow for
tracking purposes so it seems fine to use for that. Also, UMD had a
similar need for a field so I think adding one for your own uses is
fine as it could be usable to others as well.
