Second mandatory exercise errata II

It has been pointed out to us that it can be quite a lot of work to run all the 39 different combinations of data and classification algorithms required by the mandatory exercise. To get the experiments done a little faster you can modify the RapidMiner process to run all three methods at the same time, like shown in this screenshot. 

This way you can at least gather the results three at a time, which should make things go a bit faster.
