// cortex::NodeManager::AddOnHost.h
// * PURPOSE
//   Provides an interface to a separate BApplication whose
//   single responsibility is to launch nodes.
//   NodeManager-launched nodes now run in a separate team,
//   helping to lower the likelihood of a socially maladjusted
//   young node taking you out.
