Teacher grouping functionality

[lprisan]

still unclear if we can reuse Drupal grouping or we do on our own, or...

[pjotrsavitski]

As it currently stands Drupal 8 has a couple of modules that provide grouping functionality which includes access rights control checks:

• https://www.drupal.org/project/group
• https://www.drupal.org/project/og

Latter of those is an alpha release and the former is release candidate. Using the really unstable one does not seem to be such a great idea and the one being close to the final release has an issue with joining groups. Current codebase does not allow private groups as such as any authenticated user could join any group without a review process.

We could be upon that functionality and apply a patch (one exists within the discussion threads for the module), but it seems a bit reckless.
