sum and avg return NaN if the field doesn't exist

      sum/avg will return either nil, NaN or the resulting number. If any of the records that are being map/reduced don't have the field you're working on, it will always return NaN regardless. It's trivial to work around, but it seems like Mongoid should be checking to make sure the field is at least undefined/nil before trying to use it.

      class Foobar
      include Mongoid::Document
      field :pending, :type => Integer
      end

      Foobar.create(:pending => 5)
      Foobar.create(:pending => nil)
      Foobar.sum(:pending) # NaN
