20210628 Pikairos Saving all models when using X-Partitioner

This workflow shows how to combine a -X-Partitioner- node to a -Loop End- node to individually gather scoring information and models from the different Cross Validation iterations.

This workflow brings a possible answer to the question asked by @DataDudes in post #34198 of the KNIME forum.
