List modules

Moshe, thanks. We have a couple of modules which use this api. Not quite ready to release yet. Maybe in a couple of weeks. I just added a mini module (og_info, see HEAD) in this package; not sure if this is the right place though. Maybe I should have released og_info as a separate project! It's mostly an example of how to use og_settings api. The README file is updated too. I would like to know your thoughts.
