/**
 * oscP5tcp by andreas schlegel
 * example shows how to use the TCP protocol with oscP5.
 * what is TCP? http://en.wikipedia.org/wiki/Transmission_Control_Protocol
 * in this example both, a server and a client are used. typically 
 * this doesnt make sense as you usually wouldnt communicate with yourself
 * over a network. therefore this example is only to make it easier to 
 * explain the concept of using tcp with oscP5.
