Run FOF on snapshots with or without seeding black holes
This makes it possible to invoke FOF just before writing each snapshot in runs with or without FOF black hole seeding (e.g. to address #690 (closed)). There are two new parameters in the config file:
- FOF:seed_black_holes_enabled - determines if FOF is invoked regularly to seed black holes
- Snapshots:invoke_fof - runs FOF just before writing the snapshot so that particle FOF group indexes can be included
I haven't updated the examples or documentation yet in case there's a better way to do this.
