> Currently the SQL interface only supports aggregate functions when a GROUP BY clause
is present. This ticket will add the capability to query for aggregates without a GROUP BY
clause.
> Example:
> select max(a), sum(b), min(c) from table1.
> The underlying implementation will be a *StatsStream* class which outputs the results
from a *StatsComponent* query as a single Tuple.
