A Role consists of a name for the role and a list of users which are members of the role.
Roles are granted privileges on Realms, Classes and Objects, and in turn grant those
privileges to all users which are members of the role.
A role named "everyone" is automatically created in new Realms, and all new users which
connect to the Realm are automatically added to it. Any other roles you wish to use are
managed as normal Realm objects.
