    Description

      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
