+ * instances of objects that don't basically represent constants. It makes
+ * unit testing, embedding, threading, and other things hard and is poor
+ * practice.
+ * 
+ * So we put everything that we would want to be global, like Logger, here
+ * and we give everybody this as _r. The Node creates and initializes this
+ * on startup and deletes things on shutdown.
