Scikit-learn API:
* Fixed 31. `sklearn.externals.six` deprecation
* Fixed 29. Out-of-memory in `np.random.choice` for very large ranges

Functional API:
* Feature 18. Added support for N-dimensional input. Useful for convolutional nets.
* Added aliases for `mode` parameter values which correspond to respective `variant` parameter values of `StackingTransformer`:
* 'oof_pred_bag' == 'A'
* 'oof_pred' == 'B'

0.3.0

Introducing Scikit-learn API: `StackingTransformer`

* Standard transformer class with `fit` and `transform` methods
* Compatible with `Pipeline` and `FeatureUnion`
