I've found on the [ConfigurationManipulator](https://github.com/jansel/opentuner/blob/master/opentuner/search/manipulator.py#L340) class some references to sub_parameter. How does this work and how does it influences the search? How many levels of sub parameters can we have?...

I've read about [using non-stochastic options here]( https://github.com/hyperopt/hyperopt/wiki/FMin#23-adding-non-stochastic-expressions-with-pyll) and seen the use of pyll on [sklearn here](https://github.com/hyperopt/hyperopt-sklearn/blob/b880877e7dd7f24a739c7ae6f6db52f9730d68cb/hpsklearn/estimator.py#L523). I've just started exploring hyperopt on and I'd like more info on that....
