Detailed Description

This file implements all of the goo on the server side for handling clients. It's got a bunch of global variables for keeping track of each of the clients.

Note:: All functions that are used to process data from the client have the prototype of (char *data, int datalen, int client_num). This way, we can use one dispatch table.
