Dear Guix,

I'd like to add some Neo4j drivers.  This patch provides the 'officially
supported' driver.  Building for Python 3 fails with this version.  The
latest 1.5.0rc1 does seem to build for both Python 2 and Python 3, so
I'd suggest we add the Python 3 variant once 1.5.0 is out.

The other patch is for python2-py2neo, which is another driver.

Thanks for your time!

Kind regards,
Roel Janssen
