migration of Google Group to GitHub

[david frantz]

Dear FORCE community,

github now allows for discussions in the original repository!

This allows for better formatting, helps to keep everything in one place, and allows cross-linking of commits, issues and stuff like this.

Therefore, I have decided to close this google group, and I kindly ask you to continue our discussions here:

https://github.com/davidfrantz/force/discussions

Many thanks!

David
