Minor cleanup with streaming aggregates (timeSeriesWinBuf, variance).
Minor bug fix.
Added winBufCount aggregate.
Naming conventions for window buffer count changed.
Fixed loading and saving of TTimeSeriesTick. Setting maximum open files in VC++ (2048). Adding appropriate directive into project file.
Half way through serialization of TEma ...
Solving problems with 'restoring' casted objects.
Solved loading of stream aggregates with dependency on other stream aggregates (inAggr) by added StreamAggrBase in load/corresponding constructor functions. Serialization of TEma.
Completed serialization of stream aggregates (tick, winbuf, ma, ema, mva, sum, count). TVar still behaving strangely. Update function quietly terminates ...
Debugged problems with variance stream aggregate. All implemented stream aggregates technically tested, serialization working.
Merged with last version from qminer/qminer.
Corrected error with building in gcc. Added sliding window minimum.
Added sliding window minimum and maximum implemented with the deque algorithm (simulated with vector).
