| // Note, that this is not the only phase of classification: The much more |
| // complex TextValidator (ClusterValidator subclass) is used to verify whether |
| // or not a certain cluster of characters qualify as text. Therefore the |
| // TextClassifier implementation should rather provide too many, than too |
| // few classified Traces. |
