* Renamed SingleConnectionInterface to NodeConnectionInterface since this name is better and makes even more sense in the context of cluster and replication scenarios. * Moved specialized aggregate connections (the ones implementing both predis and redis cluster and master/slave replication) in a newly created Predis\Connection\Aggregate sub-namespace. * Removed the "Connection" part from names of aggregate connection interfaces in the Predis\Connection\Aggregate sub-namespace. * Changed "Composable" to "Composite" in the name of interfaces and classes that can use pluggable protocol processors.
