Description

LARQ used not to update the Lucene index as RDF statements were added/removed from a Jena Model.
LARQ is currently extending StatementListener [1] to keep a Lucene index in sync with a Jena Model, however this notification mechanism is not applicable in the case of SPARQL Update requests.

LARQ needs to update the Lucene index when a SPARQL Update request is received.
