/**
 * Example on how to embed Singularity into another piece of code or how to extend Singularity with additional
 * functionality that is not in the service out-of-the-box.
 *
 * The {@link SingularityService} class provides a number of extension points to hook additional functionality
 * into the service and by building a separate artifact, it is possible to package the code differently or add
 * additional runtime dependencies without having to modify the main SingularityService build itself.
