> I want to apply clustering algorithms like KMeansPlusPlusClusterer to pictures. And creating
a point instance for each pixel is not a good idea.
> Therefore the interface should not be based on Collections, but on some interface that
provides sort of "get(index)" accessors to data that is potentially stored in a pixel array
etc.
