Should we move the neighborhood implementations to imglib2-roi?
I think this would make sense, since neighborhoods are conceptually based on ROIs. Additionally, if we could separate the "ROI-like" components from the neighborhood implementations we'd essentially have the discrete space equivalents for ROIs. Furthermore, imglib2-algorithms already depends on imglib2-roi and they're both 0.x so now would be the time to make such a change.
Thoughts, @tpietzsch, @axtimwalde, @dietzc, @ctrueden?
