I realized that tax details, campsite types, and campsites pages are all
part of the settings of the company, in the sense that all of them are
set up by a company administrator, and should be under the same item in
the user menu.
The template for these tabs is in the same layout.gohtml file because
i did not want to repeat the tabs everywhere it were used, or i would
forget some of them when adding new tabs, and did not want to add a new
file just for that.
