Demonstrate xgboost usage #16

Apparently xgboost is the shiznit for training boosted trees. We should demonstrate how xgboost can be used with this plugin, with existing Ranklib XML method of specifying a LambdaMART model.

I would expect

scripts directory showing off xgboost
or another git repo demonstrating xgboost + ES w/ this plugin
or a helpful blog post on xgboost + ES

XGBoost has a text format listed here but it appears to perhaps be a debug project

There is a brief mention of xgboost in https://github.com/o19s/elasticsearch-learning-to-rank/blob/1_0/docs/models.md but no detail...
