The directory nesting is unnecessary here and confusing to navigate. I've moved
all apps to the project subdirectory, currently called "www", but soon to be
renamed "conservancy".
I've also moved manage.py to the top-level directory.
During the recent improvements made on the website, the menus and
submenu highlighting for selected menus fell into disarray.
Correction requires changes to the CSS and templates both, because
Django doesn't really have a convenient way to set variables in
templates to use to solve this.
There are still a few submenu items highlighting not working even
after this commit. More work needs to be done.
