Add geographiclib-tools to list of dependencies

[nstarke]

GeoQ uses GeoConvert under the hood for performing certain GeoSpatial operations (See Issue #25). It might make sense to add geographiclib-tools to the installation instructions in the README.md:

% sudo apt-get build-dep python-psycopg2

to

% sudo apt-get build-dep python-psycopg2 geographiclib-tools

Thanks Nick. Yes, it definitely would be good to add this dependency. I know one issue we had was that there didn't seem to be a version of geographiclib-tools for every platform, but that may have changed since I last looked (quite a while ago)

I would be happy to verify the library across distributions. What distributions would be necessary to include this in the README? Ubuntu/debian, RHEL/CentOS/Fedora? Any others?

[stephenrjones]

Those would definitely be the main ones -- could probably add FreeBSD to the first group. I like SUSE, but not sure how much it's used. Not sure we'd have to go beyond that

Please let me know if you would like additional validations or more information on these.
