> Create a version of Cooccurrence Analysis (RowSimilarityJob with LLR) that 
> runs on Spark. This should be compatible with Mahout Spark DRM DSL so a DRM 
> can be used as input. 
> Ideally this would extend to cover MAHOUT-1422. This cross-cooccurrence has 
> several applications including cross-action recommendations.
