   @HyukjinKwon I added some links, I think they should be relevant. 
   We already have `approxQuantile` but then this would be an exact function, limited to arrays. This function only calculates median, which is the (probably) the most common use case. I can extend it to support exact quantiles, if people think that would be better.
