 ## Maven Artifacts
-Currently, Voronoi-3D is in active development and does not publish to maven central.  Rather, periodic snapshots (and releases when they happen)
-will be uploaded to the [repo-hell]() repository.  If you would like to use Voronoi-3D maven artifacts, you'll need to add the following repository
-declarations to your pom.xml  The maven coordinates for individual artifacts are found below.
