Hi everybody,

playing around with tf_remap of the tf package, I found a small error in the 
wiki (http://www.ros.org/wiki/tf#tf_remap):
The param is "~mappings", not "~mapping".

Additionally, I was a bit confused, how to set the parameter correctly. A 
simply example in the wiki would clearify the correct usage, e.g.:
Assuming the frame "/odom" should be remapped to "/odom_robot1" and 
"/base_link" to "/base_link_robot1", mappings can be set by:
rosparam set /tf_remapper/mappings "[{old: /odom, new: /odom_robot1}, {old: 
/base_link, new: /base_link_robot1}]"
