On the user#index page, the edit buttons now link to the edit page for that user, not the current_user (as it was doing in the past). there is nothing on the user#edit page yet, though. thats because we have been using the devise edit page. i will likely copy the devise edit page to the user#edit page.
implemented more cancan control. controllers and views are using cancan to restrict user access to certain pages and parts of pages.
slight change to edit#user page. also got rid of unneccessary line in application.js file'
