Title: MRG Random hashing forests

This PR implements a simple but awesome method: random hashing forests.
I named it ``RandomForestHasher``, though it actually inherits from ``ExtraTreesClassifier``. Not sure if it was a good idea...

The example looks like this:

With more estimators in the forest, the top right looks better separated, but the other two plots are way more smooth which I think doesn't convey the nature of the decision function so well.
