- make octalCode and children members private
- add public getters for accessing these private members
- change constructor to require an OctalCode for all non-roots
- default constructor constructs a rootNode
- make primary access for deleting, adding, and accessing children through public methods that do bookkeeping
- calculate AABox on voxel creation so that we don't need to do all the math when we deal with voxels
- added methods on VoxelNode for common items like getCorner(), getCenter(), getLevel(), etc
- changed VoxelNode to have implementation option for NO_FALSE_COLOR
Need some help from Stephen and/or Leo on how to make cmake support
building the voxels library in NO_FALSE_COLOR mode for the server
but keep false color support in the client
