I object to break API in this PR. I think that this PR should cover
histogram for `DataSet<Double>` only. That's why we split this PR from #1032.
About documentation, adding a document file such as `building_histogram.md`
first and merging it later would be good.
For Scala API, the current implementation looks good for me.
