/**
 * HTTP Client. 
 * 
 * Starts a network client that connects to a server on port 80,
 * sends an HTTP 1.0 GET request, and prints the results. 
 *
 * Note that this code is not necessary for simple HTTP GET request:
 * Simply calling loadStrings("http://www.processing.org") would do
 * the same thing as (and more efficiently than) this example.
 * This example is for people who might want to do something more 
 * complicated later.
