0028 // Class description:
0029 //
0030 // Class for proxying smart voxels. The class represents either a header
0031 // (in turn refering to more VoxelProxies) or a node. If created as a node,
0032 // calls to GetHeader cause an exception, and likewise GetNode when a header.
0033 //
0034 // Note that the proxy does NOT gain deletion responsibility for proxied
0035 // objects.
