I've been toying around with MongoRecord, but I'm not sure I like it. I
have yet to figure out how to set default values. Also, it incorrectly
includes ActiveRecord as ancestor, which caused merb-auth to mix in
stuff that didn't quite work, mainly because of callbacks.
Moving back to the raw ruby driver, I found it lacks some more examples,
and some way to make DBRef handling easier.
