-----------------------------------------------------------------

[~vkulichenko] [~yzhdanov]
1)What is the point of creating continuous query without local listener ?
2)What if we set transformer via _setRemoteTransformerFactory_ only, should local listener
be optional?
3)If local listener not set, primary node must not send notifications to node, started continuous
query, am I right ?
4)If no listeners or filters set, should exception be thrown ? I, believe yes

(filter always returns {{false}}).
