Class to implement octree.
Holds the pointers to subcubes. These are either other treeNodes or
treeLeafs. treeLeafs hold the actual data as a list of indices into
Holds the pointers to sub-octants. These are either other treeNodes or
treeLeafs. The treeLeafs hold the actual data as a list of indices into
octreeData.
To prevent calculation errors all bb's used in octrees are calculated
only once.
Note
To prevent calculation errors all bounding boxes used in octrees are
calculated only once.
The pointers to either treeNode/treeLeaf are implemented 'by hand'
(explicitly marking type) instead of using a proper virtual mechanism
