C# Class LogStreamer.FilteredLogReader

FilteredLogReader reads the transaction log looking for transactions with commit ID's that modify a set of tables with commit ID's less than the transaction commit ID, or all transactions if there is no dictionary. Then makes the next transaction available, with any non-matching table operations removed from the transaction. It also does loop filtering based on peer database GUID. All transactions that contain an insert or update of LogStreamer.State where DatabaseGuid equals the peer will be ignored in entirety. Finally, no operations on LogStreamer tables will be sent.
