Announcing ARQ 1.0

ARQ is a query processor for Jena that implements SPARQL.

Announcing ARQ 1.1 - this is an upgrade to the version distributed with Jena 2.3.
It contains some bug fixes and closer alignment to the current SPAQRL specification
in the areas of evaluating expressions.  There is support for xsd:decimal in FILTERs
and the SPARQL syntax change whereby the term  1.4  (no quotes) is now treated as
an xsd:decimal, not as an xsd:double.
