/**
 * Class representing a Node in a Peer-To-Peer (PTP) network. 
 *
 * Does very little actual work, but maintains a number of important 
 * statics and contains the command-line parsing and initialisation 
 * code (or it will).
 *
 * Unlike PTP networks as Napster and Gnutella queries are not 
 * propogated, only knowledge about servers.
