Change subject: Allow insert anti-matter tuples when bulk loading LSM index
......................................................................


Patch Set 6:

It looks the property "antimatter" (more precisely, "isDelete") should be 
factored out from TupleWriter and TupleWriterFactory.  It is a property of a 
tuple that we're writing rather than a property of the writer.

PS6, Line 88: setAntimatter
I think the abstraction was not right.

isAntimatter is a property of the tuple that we're writing, but not a property 
of the Writer.  Hence, we probably should remove setAntimatter(...) from the 
TupleWriter.

Instead, we add a parameter to write tuple method:

public int writeTuple(ITupleReference tuple, byte[] targetBuf, int targetOff) 

->

public int writeTuple(ITupleReference tuple, byte[] targetBuf, int targetOff, 
boolean isDelete)

PS6, Line 119: updateFilter
Should updateFilter(...) behave differently for add(..) and delete(...)?

I don't think a delete operation can affect the existing filter?
