Why does decision tree dependes on DataFrame and Datasets?

[jordanmontt]

If you look at the baseline, it depends of dataFrame and Datasets. We should delete those dependencies

Some part of the DecisionTree model seems to rely on the fact that the user gives a DataFrame.

For example: DtmDiscretizer>>#discretizableColumnsOf:

I'm not sure we really want that dependency, but if we want to remove it then we'll need to refactor the decision tree model before

[jordanmontt]

Yes agree, we need to refactor it to remove the dependency. After, we can add some extension methods in DataFrame if needed
