BDB invocations moved from queries to the components.
ComparisonPredicate made generic.
Added finalize method to storm components.
Fixed some compilation issues.
Added hooks for statistics collection.
Small bugs fixed.
Added more comments to BDB.
Latency measurements added for StormDstTupleStorage, with and without BDB.
Optionally data sources can be slowed down.
