Version:

0.2.1 A Factory class for creating a one versus all tree kernel support vector model light data writer. It uses a TreeFeatureVector as it's feature vector which includes a SpareFeatureVector. In addition it uses the following encoders for it's non tree features: NumberEncoder, BooleanEncoder and StringEncoder. The default value for the cutoff is 5 (i.e. features that occur less than this number of times over the entire training set will not be encoded during testing). And it also uses a EuclideanNormalizer.
