-/**
- * The InspIRCd mesh network is maintained by a tree of objects which reference *themselves*.
- * Every local server has an array of 32 *serverrecs, known as me[]. Each of these represents
- * a local listening port, and is not null if the user has opened a listening port on the server.
- * It is assumed nobody will ever want to open more than 32 listening server ports at any one
- * time (i mean come on, why would you want more, the ircd works fine with ONE).
- * Each me[] entry has multiple classes within it of type ircd_connector. These are stored in a vector
- * and each represents a server linked via this socket. If the connection was created outbound,
- * the connection is bound to the default ip address by using me[defaultRoute] (defaultRoute being
- * a global variable which indicates the default server to make connections on). If the connection
- * was created inbound, it is attached to the port the connection came in on. There may be as many
- * ircd_connector objects as needed in each me[] entry. Each ircd_connector implements the specifics
- * of an ircd connection in the mesh, however each ircd may have multiple ircd_connector connections
- * to it, to maintain the mesh link.
