	You can see the requirements in http://202.120.40.15/~jzhou/courses/S09.se320/homework1.html
	Usage: ./proxy1 -l port1 -t machine:port2, where port1 specifies the TCP port this proxy listens on and -t specifies the machine (IP) address of the second proxy (note port2 is a UDP port)../proxy2 -l port, where port specifies the UDP port this proxy listens on.
	For example,you can enter "./proxy1 -l 3000 -t localhost:8000" to run proxy1,and enter "./proxy2 -l 8000" to run proxy2.That means local TCP port is 3000 and the UDP machine's IP is localhost(127.0.0.1) and UDP port is 8000.
