I don't have any immediate need for it. Mainly, I am trying to
understand the larger picture of how the occupancy grid fits into the
whole system. A large O-grid is hard to share over TCP connections
(except infrequently). PointClouds tend to get big, too. Nodelets seem
to offer higher bandwidth in certain useful cases, but not all.
I am still somewhat confused about how these various messages are
intended to be used in combination. When would we publish an
OccupancyGrid versus GridCells or PointCloud?
