calls to runQuery should return the value of `moreResults`

How do you think this should be exposed in the ruby client? There are only three possible values defined in the protobuf definition, and I would like to avoid client code that looks like the following:

query = Gcloud::Datastore::Query.new.kind("Task").
  where("completed", "=", true)
tasks = dataset.run query
if tasks.more_results == "NOT_FINISHED"
  # do something here
end

I think it would be best to rely on named convenience methods instead. So something more like this:

query = Gcloud::Datastore::Query.new.kind("Task").
  where("completed", "=", true)
tasks = dataset.run query
if tasks.not_finished?
  # do something here
end

So my question is what should these convenience methods should be named? Here is what I'm thinking:

• NOT_FINISHED -> results.not_finished?
• MORE_RESULTS_AFTER_LIMIT -> results.more_after_limit?
• NO_MORE_RESULTS -> results.no_more?

I would much rather assert a positive than a negative, so results.not_finished? and results.no_more? bother me, but I don't know if this is something that can be changed due to the way the protobuf API was designed.
