28 // Class description:
29 //
30 // Class for proxying smart voxels. The class represents either a header
31 // (in turn refering to more VoxelProxies) or a node. If created as a node,
32 // calls to GetHeader cause an exception, and likewise GetNode when a header.
33 //
34 // Note that the proxy does NOT gain deletion responsibility for proxied
35 // objects.
