Move the section on NSEDoc of C modules from its own section to a paragraph in

the section where the examples of NSEDoc are shown. Reword some things. Mention
that @name as well as @class is needed to document tables.

     It is good practice to document every public function and table in a
     script or module. Additionally every script and module should have
     its own file-level documentation. A documentation comment at the
