Group queries about mongomapper

[tpitale]

You can access the underlying mongodb adapted collection using the #collection class method @monkeyhelper. Until something nicer gets implemented with mongomapper. It takes (in order) an array of keys (to group by), a hash of the the initial values, a conditions hash, and the javascript function.

Is there a way to 'limit' a group query?

Not that I'm aware of. Somebody else feel free to correct me, though.

The new map reduce stuff will work for this. I'll wait to work on anything until that is all good to go.
