stream aggregates JS serialization:
-every stream aggregate in JS API supports saving it's state. Pure JS stream aggregate (using callbacks) must supply the save and load methods
-to load the aggregates first initialize them usin qm.newStreamAggr or store.addStreamAggr and the load their states
exception is thrown when _Load and _Save are not implemented but called (TStreamAggr API)
