...
one min/max pair per child. Converted the rest of the OSG to use the new
osg::LOD node.

Added support for occluders occluding other occluders, which helps reduce
...
the number of occluder that will be used in cull traversal to only the
ones that will be effective. Note. Holes in occluders arn't handled in
this occluder occlusion test, will implement this later.
