Incompatible with ROS Kinetic

[yswhynot]

I've been trying to build from source on Ubuntu 16.04 with ROS Kinetic and I've ran into the following compilation error:

The interface_manager of Kinetic requires empty constructor but the RobotState does not have one. May I know will it work without problem if I create an empty constructor for RobotState, since I see the input Robot model is public?

@TheClearpathDash can you create kinetic-devel branch ? so that we can push our fix https://github.com/k-okada/pr2_mechanism/tree/kinetic-devel

@k-okada I no longer am paid to be responsible for the PR2.

@k-okada: please test ros-controls/ros_control#285

[k-okada]

@ipa-mdl sorry for late, your ros-controls/ros_control#285 works fine for us!
