I have tried to brush up the entry dense subcategory a little

(moved the references to the References, moved the part that alluded to the application with nerves to its own section and expanded slightly, added the relevant back-links).

I replaced the slang-format of the reference “Categories Work” with the original Categories for Working Mathematician.

I have moved the definition of “dense subcategory in the sense of shape theory” from a “warning” at dense functor to an alternative definition section here, and re-formatted a little by adding numbered environments pointing to each other.

Maybe this should be in a separate entry and there should be a disambiguation page. But I’ll leave it at that for the time being.
