Specify example queries for GENO

We should have a test suite of SPARQL queries for GENO.

E.g.
What strains S with genotype Gt are available in organism X that have mutations M in gene G

See: https://docs.google.com/document/d/15HdByqF-Zv_TgTCUbD9hs3MaX7pFdWCYB85DtJbgp0k/edit#heading=h.8ud9l061glaw

These would be used in 2 (or more) ways.

1. As part of a junit suite, working in conjunction with test RDF datasets. (creation of a junit suite for the RDF should be a separate item)

2. As example queries on the low-level SPARQL interface. Many bio rdf stores already have such a set of test queries.
