Much improved Force Directed Graph, using Toxiclib's physics library. Also re-working the Node class to make it simpler. Add a Graph class which contains a list of the nodes as well as the edges (instead of the 'network' arraylist.
Hopefully this graph layout works better.. Need to test with more nodes.
Removed unused library, some clean up
Merged graphLayout branch
Moved the modem address into an external config file
