Single QR code launches page that allows you to select a role

unity app now has one qr code that phone scans to launch web controller app with tabs. switch tasks by using tabs. can't put qr codes in controller because phone can't point camera at its own screen. phone controller app launches into first default "about" tab that should describe app and explain all the tabs. inline links to tabs are unnecessary because tabs are clearly displayed along the top of the page. but if you really want inline links to tabs, do not use http links to same web app with different #tag because that will reload page instead of simply switching tab in same app. just call function that switches tabs. See tab code.
