Spill to disk SPARQL Update
---------------------------

                 Key: JENA-45
                 URL: https://issues.apache.org/jira/browse/JENA-45
             Project: Jena
          Issue Type: New Feature
          Components: ARQ
            Reporter: Stephen Allen


Attached is a patch that implements a spill-to-disk container for performing 
SPARQL Update commands.  It utilizes a DeferredFileQueue that can 
serialize/deserialize Bindings, Quads, and Triples.  Also included are some 
unit tests.

Items yet to be addressed:
1) Read the threshold and temporary file location from a config file
2) Examine compression of the bindings/quads/triples to see if we can improve 
I/O speed
