(HLAPI) class that manages connections from multiple clients. While the NetworkServer class handles game-like things such as spawning, local clients, and player manager, and has a static interface, the NetworkServerSimple class is a pure network server with no game related functionality. It also has no static interface or singleton, so more than one instance can exist in a process at a time.

The NetworkServer class uses an instance of NetworkServerSimple internally to do connection management.
