[ros-users] Converting PointCloud to LaserScan

Look at the launch files, its fairly simple to use.  My only problem with it
is that having a point cloud can generate multiple laser scans (I have one
from a kinect for example) but this stack only supports one.  I'm working on
one for my own purposes at this point, I will post it to github or something
when I am done.
