Heroku buildpack: geo

This is a Heroku buildpack that vendors main geo/gis libraries like geos, proj and gdal.

You will use this buildpack with other major buildpack such as Ruby buildpack.

Example usage:

$ heroku buildpacks:set https://github.com/cyberdelia/heroku-geo-buildpack.git
$ heroku buildpacks:add heroku/ruby

Run heroku buildpacks to make sure that heroku-geo-buildpack is added before the language buildpacks.
