Absence reports (also disabling autofixer)

- Dumb screen for checking for absences, kind of ugly for now
- Needed code added to Summary class
- Cleaning up the routes.rb file
- Cleaning up the users controller
- New namespace ‘/admin’ for absences report and for getting everybody
reports (before it used a ugly hack around id parameters)

- Also, auto fixer disabled until I figure out why it’s blowing up
