This looks really good! Other than a minor question on one of the stats bin
unit tests, it looks good to me. +1 pending comment/clarification on that item.
> Add a STATS_BIN function to Stellar.

> When passing parameters to models, it's often useful to pass the binned
> representation of a variable based on an empirical statistical distribution,
> rather than the actual variable. This function should accept a set of
> percentile bins and a statistical sketch and a value. It should return the
> index where the percentile of the value falls.
> For instance, consider the value 17 who is percentile 27. If we use 25, 75,
> 95 to define our bins, this function would return 1, because its percentile,
> 27, is between 25 and 75.
