Updated the structure of queries: queries.rif now simply imports the
individual queries, now stored in seperate x.rif files where x is the
query number.  in order to run a query with data, another .rif file must
be written that imports the desired query(s), the supporting rules (if
desired/necessary), and the data to be applied.  this is so personal
.rif files can be used to apply the generic rules to the large test
data.  An example .rif file is provided demonstrating the application of
the rules and the small data sets on the repo with query 7.5.  This is
also the RIF setup now tested by RunLSBenchRIFQuery.
