[Feature Request] Nested usergroups

Description

Nested tags are cool! Now, I would like to nest groups so you can build an entire org chart, too.
By adding nested groups, you can create a role based permission system where interdisciplinary teams are working together on a project. However, not every member of the marketing, finance and tech department has to see the project-related docs.
Instead, if you start nesting groups, you will put the relevant users into a seperate group.
Having a role based system will allow you to create release processes, too where different types of roles are required to agree on something (like a project related permission task of a multi-layered release of an invoice for example).
