weka module: data from rss (07 / 0 5 / 2014)
Minnor rework on TextClassifier:

- visibility variable change to private (and getter used instead of "dot" access)
- added method @override toString to TextClassifier
Simple benchmark for TextClassification. Nowadays this shit is not working. The decision tree build by weka is a 4 leaves bush (Madrid => Aguirre)
