As a player, I want to see that other players have scanned the same QR code.

Acceptance criteria

Pre Conditions:

QR codes have scanned
Players can add QR codes

Post Conditions:

There is a global database that contains the hash of all scanned QR codes and the number (N) of players who scanned it
When a player adds a QR code, the associated hash N value is incremented by 1 (or created if it doesn't already exist)
When a player removes a QR code, the associated hash N value is decremented by 1
Every QR code on the user's profile contains a tag that notes how many people have scanned that QR code

Optional Conditions:

If a user has a QR code that has a hash N value of 1, Then a special tag "Unique" is added to that QR code.
