/*
MAJOR NOTES ABOUT EZSOCKETS:
	You CANNOT use a copy constructor or an equals operator on ezSockets!
	They will fail!  This is to prevent orphaned sockets.  You must keep
	them as pointers if you need to move them around (ie in servers)

  You may find more information about this library in the future on CNLohr.net
