ur_ctrl_client first commit.  Tests communication to a ur_ctrl_server
Adding new UR control scheme.  Uses ros_control framework to enable realtime control switching. Uses simple_messages to dictate communication.  ur_ctrl_server should be compiled on the UR server, but can be compiled on a ROS machine for testing/simulation.
