* The fix in the last change did not work. Trying the numbers
as floats instead.
2015-02-09
* The float fix worked once I figured out the correct syntax to
use in the Elasticsearch() constructor call!
* Removed unused modules 'python-geoip' and 'elasticutils' from
setup.py's install_requires. Now using 'python-geoip-geolite2'
and 'elasticsearch' instead.
* Updated README.rst - added es_timeout parameter to config description.
