    Description

      Our decision tree script requires dummy coded inputs (in case of categorical attributes) as well as a mapping matrix indicating which attributes where mapped to which dummy coded features. This task aims to introduce a builtin function transformcolmap that allows to directly compute this mapping matrix from the frame meta data, returned from transformencode.

      Once this builtin function is in place, we might want to simplify the decision tree script, doing all this pre-processing internally instead of require the user to handle it.
