(LambdaMART) File format to run example #69

Could you provide file formats to run LambdaMARTRunner.scala? Or files itself? It would be better to support this defacto standart: https://arxiv.org/ftp/arxiv/papers/1306/1306.2597.pdf

I'm also mystified: LambdaMARTRunner.loadTrainingData() doesn't seem to be designed to parse a LETOR like format.
