  the pointcloud and its manager are meant to provide
  name-based lookup for the selection mechanism. They are
  defined here in abstract terms, and are then used in e.g.
  the gfx modules - a graphical object ISA point cloud, and 
  the gfx object manager ISA point cloud manager. This way
  named graphical objects can be used in a selection statement,
  when the query is receiving a pointer to a point cloud manager.
