/**
 * This file is used to automatically bootstrap a NodeCG Server instance.

 *
 * At this time, other means of starting NodeCG are not officially supported,
 * but they are used internally by our tests.
 *
 * Tests directly instantiate the NodeCGServer class, so that they may have full control
 * over its lifecycle and when the process exits.
