Move hand to /rh
Bit of extra debug.
Use sh_description instead of robot_description.

Same as the real hand.
Fix simulated self tests to work in namespace.

HandCommander and self tests take a namespace argument to make them run in
a different namespace. We want them in /rh but the code is running in gazebo ie
under / (as gazebo is started in the root ns).
Merge remote-tracking branch 'origin/hydro-devel' into F_gazebo_namespaces
Update for position controllers.

Now the default in the simulator.
Mock hand instead of sim.

Cos gazebo keeps on breaking.
Split mock and gazebo tests.
Merge branch 'hydro-devel' into F_gazebo_namespaces
Merge remote-tracking branch 'origin/hydro-devel' into F_gazebo_namespaces
Fix up tests for namespace of topic names generated.
Fix for arm and arm_and_hand launch.
Cleanup
Move arm and hand into rh/
Remove load_hand_model_robot_description.launch

We just need load_hand_model.launch
Review. Launch args for namespace.

Also added one for the world.
Params for arm and hand.
Layout.
Review: Better error message.
Merge branch 'hydro-devel' into F_gazebo_namespaces
