Yes. I was concerned about the API breaking part too.
What about keeping the original histogram as such, and add something like
`DoubleHistogram`, which basically works on `Double` values?
As I look at this more and more, I'm also arriving at the conclusion that
we need not have a base class for the two histogram types. Lemme change this
and I'll push a patch in a while.
