Human Factor - Remote controller

I have now implemented a client/server interface which allows a user to remotely control parts of the visualization. This functionality uses a simple protocol based on Java streams. As I have tried to make it so that as little data as possible are transferred on each update, the delay between an action on one computer and the update on the other one are almost non-exsistant. The controlled object is the crane now placed a little to the right of the truck.
