Hi Stephan, sounds good.
1. I wanted to avoid too much duplication, but I see your point.
2. Ok, throwing a new exception breaks the API. So should I just mark
`Histogram` as deprecated? I guess the proper way would be to make Histogram
generic, enabling users to instantiate Histogram<Long>. Again, this breaks the
API, so we would have to wait for the next major release â what is the
process for cases like that?
