first contiguous draft of "The Categories ..."

There are still a bunch of points to work in (that I'm keeping a list of
in the notesfile) and sections that should be reorganized for clarity,
but there are at least (I think) no major discontinuities that I need to
denote with "[...]". I could even publish this as-is and not die of
shame. But we can probably do better than that.
