Aggregates about sparql-engine HOT 5 CLOSED

Hi
Aggregates do work, but they require you to add a GROUP BY clause to the query. Otherwise, the framework will not return correct results.

So, for example, If you want to count all distinct subjects in a RDF dataset, you can use the following query:

SELECT (COUNT(DISTINCT ?s) AS ?c)
WHERE {
  ?s ?p ?o
}
GROUP BY ?s

I've planned to do a few more work on this project next week, I will put the "aggregates without group by" feature on my todo list ;)

Well, I've just pushed some modifications on the master branch that should allow SPARQL aggregates to work without adding a GROUP BY clause.

I will be glad if you could try it and provide some feedback.
