Title: trees: Handling FloatAttributes.

This patch adds:

* Gini index and information gain ratio as `DecisionTree` split options;
* handling for numeric Attributes (split point chosen naïvely on the basis of maximum entropy);
* A couple of additional utility functions in `base/`
* A new dataset (see `sources.txt`) for testing.

Performance on Iris performs markedly without discretisation.
