The best way to visualize localization is using the Transform display,
with "map" as the fixed frame. Then the "odom" frame shows you the
pose estimate from localization.
The PoseArray display (using the /particlecloud topic) is only used
when debugging localization (e.g., trying to understand why the pose
estimate is bad in a particular environment).
