Flesh out docs, please?

Howdy. We're really happy with this code, and have forked it (and contributed a bit back, which you accepted, thanks!). However, I'm stymied by basic usage. I know Nagios, but the overlap between this module and the 'Naginator' code seems obscure. For instance, I'd like to create and use contactgroups. Do I use the Naginator definitions, or "icinga::groups" defined here? And can you give me practical usage examples for this, please?

Thanks!

Oh, and how might one approach creating host dependencies? :) Escalations? And can I define these in node classes instead of in site.pp?
