…lities to mapped data
Issue
Confusion matrix does not work correctly if the data comes from random sampling, not cross validation. Probabilities are not of the same shape as data, so hstack crashes. Also, annotated data outputs the original data instead of the mapped. For example, (re)sampling iris can produce 510 testing instances, while annotated data contains the original 150.
Description of changes
Widget's self.data now contains mapped data.
