Somehow I also managed to not add IDFTransformer to the original commit. |

Description
The performance of the transformers was suboptimal when there was a large number of features. Got the transformation time for a large text classification problem down from more than two hours to less than two minutes. Along the way, I added some logging (at Level.FINE) so you can see what's happening, if you choose to do so.
As I was working on a text classification problem, I added and IDFTransformation that can set TFIDF weights in the example.
Motivation
Transformer performance was far too slow in some cases.
