/*
 * This is the most basic example of using Discover.
 * 
 * In this example all we are interested in is when new nodes are added to the
 * network or when they are removed. The master selection stuff happens behind
 * the scenes but we can completely ignore it and just handle the events for 
 * new nodes added or removed from the network.
