Package structure: vertical over horizontal slicing

[arazabishov]

Code in qualitymatters at this moment is grouped into packages by layers (api, models, network, etc). Instead, it might be better to group bits of code by features / use cases. Such structure is easier to understand, extend and refactor. Please, see this article here: http://www.javapractices.com/topic/TopicAction.do?Id=205

It also might be not applicable to qualitymatters, since project itself is quite small, so horizontal slicing (by layers) can also work.

What do you think?

I'm not against that, on real-life projects we usually group code by features.
