Player groups

[grubersjoe]

In the long run, different groups of people should be able to use the app. Therefore, it should be possible to have different "groups" inside the app which only see the matches of their group members.

• a user must be in at least one group
• after registration the initial group must either be
  • selected from existing ones
  • or newly created
• this should happen in the same dialog which asks for the users initial nickname
• if a user is in multiple groups she/he sees the matches of all those groups

Nice to have

• filter matches for a group

Implementation details

• create a new collection groups in database
• every match has a reference to exactly one group
• when creating a match and the user is in multiple groups she/he can select in which group the match should be created
• more thought about all this is probably a good idea
