User story

As a DM, I want to organise my players into specific campaigns, because I have multiple people and campaigns to keep track of.

Who, what, and why

Who: Dungeon masters / game masters, running campaigns containing multiple players.
What: Players should be able to be grouped by campaign. Players can be in 0 to many campaigns at the same time.
Why: This is a standard organisational process that people need to manage who is involved in which game.
