Categorical input data support #205

what's the state on this? it seems that Python package has some limited support for it: https://xgboost.readthedocs.io/en/stable/tutorials/categorical.html

The only reference I see to this in the C lib is here. I'm somewhat doubtful that this actually does anything, if not they probably added the feature in python, which would not be unprecedented.

if I have to guess I'd say all they are doing is saves you the trouble of manually one hot encoding a categorical columne into N columns of Bools?
