The main idea of Steffens code at that time was to have something
which is really _simple_ and be used to implement backends, which
build upon such simple data structures. Main main point is that dense
is not a good name, as we can (and want to) have sparse matrices with
simple data structures, but I don't object other names, if you have a
better suggestions.
