Hey,

I just added an initial go at a fluent FilterBuilder.  If any of you has a
second, would you take a quick look?  I fully javadoc'd the public
interface and included a full set of junit tests, so there should be plenty
of examples to see where I was going.  I would appreciate suggestions for
improving it.  One thing I think would likely be useful would be allowing
more types for names and values in the comparison operations...

Also, I recently updated the Oid object to make it a little more efficient
and clean up the code.  I noticed, it is not used for much, but we could
make use of it more.  For example, we could use it for all of the xxx_OID
constants in the schema constants (which are currently strings).  Because
the Oid object caches the string value as well as the encoded byte[] value,
it could improve efficiency wherever it gets used when translating to/from
the wire.

Anyway, let me know what you think...
