Adds a simple way to quarantine individuals but doesn't make it roundstart, as it has potential to make 2 antags have a very difficult time: Bad virologists and (mainly) sentient diseases. Uses a sliver of silver because of this.
It uses the exact same proc as the MEDHUD, so it CAN be countered by buffing stealth. Virologists can also activate the free-access so long as they do it while not infected with anything bad.
That said, it has a build delay and is relatively easy to destroy. Think of it as a more obvious visual for people without huds to know "hey, I should probably avoid everyone else until I get better" and not necessarily an actual barrier device.
sprites edited by me if you like them, by someone else if you don't!
