 When working with groups or a collection of user objects, it would be helpful to be able to check which users you've actually got on hand just by yeeting them to stdout without much effort. A simple `__repr__()` that provides a user's uid or something else identifiable would be a nice QOL update. Something like `<CSHMember [zach - "Zach Hart"]>` might be nice. Not sure what you'd put in the groups, maybe the group name and count of members in it.
