UDP client and server code. 

The client sends a single 32bit integer to the server without converting
to network byte order.

The server looks for incoming datagrams, and looks in each one for
a 32 bit integer, which it prints out (without converting from
network byte order).

The point is:

	1. sending binary data

	2. watch things screw up if the server and client don't use
	   the same representation for integers.


To see the Network byte order problem, run one of the programs on a
PC (Linux, BSD) and the other on a Sun.


The client command line looks like this:


client foo.cs.rpi.edu 2030 8765

The first number is the server port number, the last number is the
integer that will be sent by the client to the server. If all goes well,
the server will print out this number.
