/**
 * Connection
 * Abstract class that defines the global behavior of a connection.
 * This class is used by all the connection types (Wifi & Bluetooth) and 
 * for both sides (client & server).
 * 
 * It has methods to write packets in the connection.
 * Implements Runnable to have his own thread for reading the incoming connection,
 * and then routing the read packets to a handler.
