robotic_arm/waypoints_follower: added generic class to follow arm's waypoints.
snark-ur5-control: with first un tested version of move_effector.
robotic_arm/commands_handler & snark-ur5-control: actuating version of move_effector, need to verify correctness.
snark-ur5-control: disallowed changing from move_cam to move_effector and vice versa, they can both be started from home position. robot-arm.json: home position is now specified with 6 angles in radian not degrees.
snark-ur5-from-console: added --no-exit option to allow running when arm is initialised, commands_handler: will report when cammnd is not possible - out out arm's range. auto_initialisation will use Simulink code.
sensors/hokuyo: moved data_point structure to new file output.h
