[ros-users] merging different joint_states

[David Lu!!]

Ugo-
Your email reminded me that I was thinking about adding this feature to
joint_state_publisher. I've attached a version that I'll upload to our
repository after a little more testing.

    <node name="joint_state_publisher" type="joint_state_publisher"
pkg="joint_state_publisher" output="screen">
        <param name="robot_description" textfile="model.urdf" />
        <rosparam param="source_list">[head_states, body_states]</rosparam>
    </node>

This is how I launch it to merge the JointStates published on head_states
and body_states.

Let me know how well it works.

-David!!
