/**

 * This class will house the SimpleNetworkWrapper instance, which I will name 'dispatcher',
 * as well as give us a logical place from which to register our packets. These two things
 * could be done anywhere, however, even in your Main class, but I will be adding other
 * functionality (see below) that gives this class a bit more utility.
 *
 * While unnecessary, I'm going to turn this class into a 'wrapper' for SimpleNetworkWrapper
 * so that instead of writing "PacketDispatcher.dispatcher.{method}" I can simply write
 * "PacketDispatcher.{method}" All this does is make it quicker to type and slightly shorter;
 * if you do not care about that, then make the 'dispatcher' field public instead of private,
 * or, if you do not want to add a new class just for one field and one static method that
 * you could put anywhere, feel free to put them wherever.
 *
 * For further convenience, I have also added two extra sendToAllAround methods: one which
 * takes an EntityPlayer and one which takes coordinates.
